49ers Work Out Sean Spence, Donald Butler
As linebacker Reuben Foster deals with an ankle injury, the 49ers are looking into some outside help. San Francisco auditioned linebackers Sean Spence and Donald Butler on Tuesday, according to ESPN.com’s Field Yates (on Twitter). 
Spence spent last season with the Titans and recorded 50 tackles with three sacks in 15 appearances (six starts). He hooked on with the rival Colts in March, but Indianapolis decided to eat the $750K guaranteed in his deal rather than keep him on the 53-man roster. Spence might not be starting material, but he could be a worthwhile reserve for SF until Foster gets back on the field.
Butler, a former third-round pick, spent his entire six-year career with the Chargers before being released by the team in March of 2016. He joined up with the Dolphins in September of last year and saw time in 14 games, including five starts. His 28 total tackles marked a career low and it was his first season without at least half a sack.

Jaguars Sign WR Max McCaffrey
The Jaguars have signed wide receiver Max McCaffrey, the team announced. McCaffrey, the brother of Panthers rookie running back Christian McCaffrey, was plucked from the Saints’ practice squad. 
[RELATED: Jags’ Allen Robinson Done For Season]
Jacksonville was in desperate need of depth at wide receiver after losing star Allen Robinson for the season to a torn ACL. With Oklahoma product Dede Westbrook also on IR, the Jaguars will plug McCaffrey in as their fifth wide receiver behind Marqise Lee, Allen Hurns, Arrelious Benn, and UDFA Keelan Cole.
The Jaguars enjoyed a surprisingly strong start to the season when they toppled the Texans 29-7 on Sunday. Rookie Leonard Fournette did most of the damage with 100 rushing yards plus three catches for 24 yards while Hurns led all receivers with three grabs for 42 yards. If the Jaguars want to continue their winning ways, they’ll probably need to do more through the air going forward.
Texans Place C.J. Fiedorowicz On IR
Less than two weeks after signing an extension, C.J. Fiedorowicz won’t be available for the Texans for a while. The team placed its starting tight end on IR after he sustained a concussion, Adam Schefter of ESPN.com tweets.
Fiedorowicz missed time with a concussion last season as well, and this latest head injury will shelve him for at least half of Houston’s season. The Texans re-signed Ryan Griffin this offseason but are thin behind him, with only second-year UDFA Stephen Anderson on the roster.
The Texans activated wide receiver Jaelen Strong, who served a one-game suspension.
Fiedorowicz played in Week 1 but left with the concussion. With the Texans playing on Thursday, he was not going to be cleared in time for Week 2. He will now be out for much longer. Griffin also is in concussion protocol, making it likely Houston looks for tight ends soon. Brian Cushing and Bruce Ellington are also in the protocol, and Bill O’Brien didn’t sound optimistic Tuesday when assessing their chances for Thursday night.
The fourth-year tight end broke out last season, more than doubling his previous career receiving yardage total by catching 54 passes for 559 yards.
Packers To Release Ricky Jean-Francois
The Packers evidently have not preferred the work Ricky Jean-Francois gave them during his 2017 stay in Green Bay. The team released the veteran defensive lineman, Adam Schefter of ESPN.com tweets.
Jean-Francois played only six snaps Sunday against the Seahawks. The Packers signed Jean-Francois to a one-year, $2MM deal and gave the veteran defensive end a $250K signing bonus. The 30-year-old interior defender is a vested veteran and will become a free agent.
Green Bay becomes the second franchise to release Jean-Francois this year, with Washington doing the same during the offseason. He caught on with the Packers, who had reportedly eyed him for years, after visiting the Bears and Seahawks.
The Packers were without rookie third-rounder Montravius Adams, sidelined with a foot injury, in Week 1. This could be an indication the Auburn product will be ready to play soon. Jean-Francois served as a backup last week behind Mike Daniels and Dean Lowry.
Jean-Francois began his ninth NFL season on Sunday, doing so with a fourth team. The former 49ers, Colts and Redskins cog vacillated between starter and backup status throughout his career. He started seven games for the Redskins last season.
Bills To Sign LB Jelani Jenkins
Jelani Jenkins will return to the AFC East after an unsuccessful foray with the Raiders this offseason. The Bills are signing the former Dolphins linebacker, Joe Buscaglia of WKBW tweets.
The Raiders released Jenkins with an injury settlement earlier this month, and it looks like Buffalo feels confident the 4-3 outside linebacker has recovered sufficiently from the groin injury that sidelined him. The Bills cut rookie cornerback Greg Mabin to make room on the roster.
A 2013 fourth-round pick, Jenkins started for three seasons with the Dolphins. Although injuries marred his 2016 campaign, Jenkins stood out as a first-year starter two years prior in making 110 tackles and registering 3.5 sacks. The Bills did not have much experience on their linebacking corps behind starters Lorenzo Alexander and Ramon Humber, carrying fifth- and sixth-round rookies Matt Milano and Tanner Vallejo as second-stringers.
The Raiders signed Jenkins to a one-year, $1MM deal to compete for a starting job on a defense without much linebacker experience. He could not secure the outside linebacker position opposite Bruce Irvin and was released.
Danny Woodhead Expected To Miss 4-6 Weeks
Danny Woodhead‘s latest injury will be costly for his new team. The Ravens will be without their primary passing-down back for at least a month, with Ian Rapoport of NFL.com reporting (via Twitter) Woodhead could be out up to six weeks with a hamstring malady.
Rapoport adds (on Twitter) the Ravens have a roster decision to make, with this timetable making Woodhead an IR candidate. Only two running backs — Terrance West and Javorius Allen — reside on Baltimore’s active roster. The Ravens are carrying two practice squad backs, however, including former Bears starter Jeremy Langford.
Woodhead missed most of last season and played in only three games for the 2014 Chargers due to injury. The 32-year-old back signed a three-year, $8.8MM pact with the Ravens this offseason. Woodhead tore his ACL last season and suffered a broken leg in September 2014, marring his Chargers tenure.
In 2015, however, Woodhead totaled 1,091 yards from scrimmage and nine touchdowns to largely create his 2017 UFA market.
Bears Place Jerrell Freeman On IR
The Bears made the decision to place linebacker Jerrell Freeman on IR on Tuesday, Adam Schefter of ESPN.com reports (on Twitter).
Freeman entered Chicago’s concussion protocol on Sunday while also suffering a pectoral injury. The latter would pose a bigger threat to his returning this season. The starting inside linebacker is out until at least November as a result of this transaction.
Chicago signed linebacker Jonathan Anderson off its practice squad, per Schefter.
The 31-year-old Freeman, a 2016 UFA signee who came over from the Colts, led the Bears with 110 tackles despite playing in only 12 games due to a four-game suspension for a positive PED test.
This marks the latest injury setback to a Bears linebacker corps that’s endured a few this offseason. Danny Trevathan spent the offseason recovering from a torn patellar tendon — his second serious knee injury in three years — and Pernell McPhee‘s knee troubles induced DC Vic Fangio to describe the former Raven as not being the same player he was pre-injuries.
Chicago has Nick Kwiatkoski and Christian Jones as inside linebacker options while Freeman recovers from his head injury. Kwiatkoski will be the starter while Freeman’s out, Brad Biggs of the Chicago Tribune notes.
