SANTA CLARA — The 49ers' list of injured players sitting out of mandatory minicamp grew Tuesday but most of them are expected to be back in time for training camp next month, according to coach Kyle Shanahan. 

Tight end Garrett Celek sat out of OTAs with a residual back injury from last season, and remains in the concusion protocol. Shanahan said Celek will remain in the protocol until training camp when the 49ers practice in pads. 

The reason? Celek missed his testing window, and the NFL isn't testing again until training camp begins.  

Celek sat out Tuesday because he needs back surgery, similar to what receiver Trent Taylor had during the 2018 offseason. As a result, the tight end might miss the beginning of training camp. 

Rookie wide receiver Deebo Samuel will also miss the remainder of minicamp as a result of a tweaked hip that kept him out of the final week of OTAs. He should be ready for training camp, however.

Right tackle Mike McGlinchey will sit out after having a platelet-rich plasma injection in his knee. The recovery timeframe is usually about two or three weeks of staying off your feet, which means he should be ready by the time training camp begins in late July. The 49ers timed McGlinchey's procedure to ensure a timely return for the season.

The remaining players who not participate in minicamp are the same as those who did not participate in OTAs: 

 

RB Matt Breida (pectoral)
RB Jerick McKinnon (knee)
RB Raheem Mostert (forearm) 
WR Jalen Hurd (knee)
C Weston Richburg (knee/quadriceps) 
DE Nick Bosa (hamstring)
LB Kwon Alexander (knee)
LB Fred Warner (knee)
CB Jason Verrett (Achilles)
Safety Jimmie Ward (collarbone)
Safety D.J. Reed (shoulder)

Shanahan is not overly concerned about the injury list. He said the 49ers will be careful ensuring everyone returns healthy, but each player is on schedule to return at a good time. 

“Everyone we are really hoping for that first day, we can get them back," he said at the 49ers facility Tuesday. "That’s why I joked with you guys at the beginning. We are having really bad OTAs in terms of guys not being healthy for it, but we’ve had so many healthy OTAs since we’ve been here that we hope it’s the opposite for training camp.”
