49ers injury updates: Garland, Mostert, likely headed to the IR

San Francisco 49ers head coach Kyle Shanahan met with the media Monday afternoon to provide a few injury updates. Running back Raheem Mostert has a high-ankle sprain and will likely land on the injured reserve. Mostert landing on the IR is a good signal that Mostert’s injury is severe. Shanahan added that Tevin Coleman is a “long shot” to come back this week. Kyle said he’s hopeful that Jeff Wilson, who is suffering from a calf injury, returns to practice this Wednesday.

That wasn’t the only blow. Ben Garland has a calf strain and is likely headed to the injured reserve as well. Hroniss Grasu filled in for a handful of snaps for Garland Sunday against the Rams. He’ll be the starting center until Garland or Weston Richburg returns. Shanahan said C Weston Richburg had a setback this offseason when he had shoulder surgery, and the 49ers won’t get him back until at least Week 13.

Trent Williams left the game with a head injury, but Shanahan added that the left tackle is dealing with an ankle issue as well. He’ll be further evaluated as Williams is getting more imaging done. Losing two offensive linemen in one week would be a significant blow to the Niners’ offense.

Jaquiski Tartt has an ankle injury, and he’ll be further evaluated later this week.

OL Ben Garland (calf strain) will be out a while - IR

RB Raheem Mostert (high ankle sprain) - IR

S Jaquiski Tartt (groin) will evaluate this week

LT Trent Williams (ankle) will have more tests done this week.

High-ankle sprains have been brutal for this team. Mostert would be the fourth high-ankle sprain the 49ers has suffered this season.
