An Anthony Castonzo stay on the PUP list due to a midsummer hamstring tweak was among the Colts‘ late-offseason concerns, but that won’t end up taking place. The Colts did not end up placing their top left tackle on the PUP list, per Mike Chappell of CBS 4 (Twitter link). However, Chappell notes (via Twitter) Indianapolis did follow through with placing safeties Malik Hooker and Clayton Geathers on the PUP. Both were expected to land there, with Hooker (torn ACL, MCL in October) being a bit further away from a return.

Here’s the latest from the AFC on the final offseason Sunday for most teams.

• August extensions have been one of the Steelers‘ traditions over the years, and an unlikely candidate for a significant pay bump’s emerged. Chris Boswell joined the Steelers midway through the 2015 season, but his production last year (35-for-38 on field goals, four game-winning makes en route to the Pro Bowl) and contract-year status make him a prime preseason-extension candidate, Joe Rutter of the Pittsburgh Tribune-Review writes. The Steelers applied a second-round RFA tender (2.9MM) to Boswell this year, and Rutter believes it will take a guarantee in the $9MM-plus range to keep Boswell in Pittsburgh. Only two kickers — Stephen Gostkowski and Justin Tucker — received eight-figure guarantees, with the Bears’ Cody Parkey guarantee sitting in third.
• Despite a light investment at linebacker to replace Ryan Shazier, don’t automatically look for the Steelers to deploy Terrell Edmunds as a hybrid safety just yet, Mark Kaboly of The Athletic writes (subscription required). Kaboly expects the first-round pick to play in the William Gay role as a dime contributor as a rookie, with UFA linebacker add Jon Bostic or second-year man Tyler Matakevich replacing Shazier.
• In what is Breshad Perriman‘s last chance to make an impact with the Ravens, he may be on the outside looking in to make the team, Jeff Zreibec of The Athletic notes. In addition to being behind new additions Michael Crabtree, Willie Snead and John Brown, Zreibec notes the 2015 first-round pick is “certainly” trailing Chris Moore and Tim White as well. (Moore is a career backup, and White is a former UDFA who has yet to play in an NFL game.) Considering rookies Jaleel Scott (Round 4) and Jordan Lasley (Round 5) also may be ahead of Perriman, this is a bind for the one-time highly regarded prospect. Ravens officials, however, wonder how much different the Central Florida product’s career would be had he been able to be on the field during the team’s past training camps rather than missing most of those sessions due to injuries, per Zreibec. Perriman looked on the verge of a promising season after shining in the 2017 offseason program, but a hamstring tear put the kibosh on those hopes. Baltimore picked up an option bonus of $649K earlier this week, but that will merely buy the fourth-year pass-catcher this preseason to try and make one final impression.
• Phillip Lindsay now serves as a wild card in the Broncos‘ running back room. The Colorado product who blazed to a 4.39-second 40-yard dash clocking at his pro day received interest from several other teams before opting to stay in Denver, Mike Klis of 9News notes. The Denver native’s $15K signing bonus marked the third-highest in John Elway‘s eight-year tenure at the helm. Klis writes Vance Joseph plans to evaluate the 5-foot-7 speedster for a Darren Sproles-type role as a third-down back and return man. The Broncos have struggled on returns since parting ways with Trindon Holliday after the 2013 season. Primary 2017 return man Isaiah McKenzie fumbled six times as a rookie. The Broncos added two rookies — third-rounder Royce Freeman and seventh-rounder David Williams — to a backfield mix that includes veterans Devontae Booker and De’Angelo Henderson.
