88 Garrett Celek TE

Celek (concussion) is recovering from thumb surgery but should be ready for the start of the offseason program, Joe Fann of the 49ers' official website reports.

Celek sat out Week 17 with a concussion, finishing the regular season with five catches for 90 yards and two touchdowns in 15 games. He averaged just 18.5 snaps per game on offense as the clear No. 2 tight end behind George Kittle, after averaging 37.9 per game in 2016 and 35.0 in 2017. Celek will turn 31 in May and only has one season remaining on his contract, but a reasonable salary combined with special-teams contributions should be enough to keep his roster spot safe. It doesn't sound like the thumb injury will have much impact on his offseason routine.

Celek (concussion) was ruled out for Sunday's game against the Rams, Nick Wagoner of ESPN.com reports.

Celek was able to practice in a limited fashion this week, but was unable to fully clear the concussion protocol. The 30-year-old will head into the offseason having caught five of eight passes for 90 yards and two touchdowns in 15 games. Sunday will mark the first time Celek has missed a game since 2015.

Celek (concussion) was a limited participant at Wednesday's practice, Nick Wagoner of ESPN.com reports.

Celek will still have to clear the league's concussion protocol before receiving the green light to play in the season finale Sunday against the Rams. For now, the fact that he's on the field in any capacity suggests he's at least made some progress through the five-step protocol after being diagnosed with the head injury during the Week 16 loss to the Bears.

Celek (concussion) is in the concussion protocol Monday, Nick Wagoner of ESPN.comreports.

Celek suffered a head injury during Sunday's 14-9 loss to the Bears, and will need to clear the league-mandated concussion protocol before retaking the field. Due to the nature of such injuries ,and the 49ers being well eliminated from playoff contention, it wouldn't be surprising if Calek were to sit out versus the Rams in Week 17.

Celek (concussion) will not return to Sunday's game against the Bears, Patrick Finley of the Chicago Sun-Times reports.

Celek was unable to clear the league's concussion protocol and will therefore be sidelined for the remainder of Sunday's tilt while George Kittle continues to rack up a healthy share of reps at tight end.
