After tearing his ACL in a preseason game last year, former Browns tight end Stephen Carlson has officially been cleared to return to football activities, and, according to Tom Pelissero of NFL Network, Carlson worked out today for the Giants in his bid to return to the field. 
Carlson was an undrafted free agent who signed with the Browns in 2019. Injuries to tight ends David Njoku and Pharaoh Brown elevated Carlson to third-string behind Demetrius Harris and Ricky Seals-Jones during his rookie season. Carlson saw most of his action in run-blocking or special teams, but he does have six career receptions for 62 yards and a touchdown, as well as a two-point conversion.
His role in the offense was reduced drastically in 2020 by the additions of free agent Austin Hooper, rookie Harrison Bryant, and the return of a healthy Njoku. After being given an exclusive-rights free agent tender by the Browns, Carlson signed a one-year deal to stay another year in Cleveland, before his ill-timed injury ended his season before it could begin.
Carlson’s attempt to join the Giants could result in a reunion with Seals-Jones. With Seals-Jones and Jordan Akins likely cemented as the top two tight ends on the roster in New York, Carlson would be competing for a TE3 or TE4 job with 2022 fourth-round pick Daniel Bellinger and fellow undrafted free agents Chris Myarick and Austin Allen.
I wouldn’t necessarily say Seal-Jones and Akins have anything cemented. Neither of them have accomplished much on the field. Just 204 catches and 13 TDs between them in a combined 112 games. Averages to about 31 catches and 2 TDs of production over a 17 game season, and that’s if they’re healthy. That job is there for the taking, especially since both are making only around $1 million on one year deals.
TE3 or 4 sounds like the next employee for Ups or FedEx
