49ers' Brock Purdy: Injury not believed to be serious

San Francisco head coach Kyle Shanahan said after Monday's 40-34 loss to Detroit that Purdy's right elbow injury isn't believed to be serious, Nick Wagoner of ESPN.com reports. Purdy carried three times for 12 yards and a touchdown and completed 27 of 35 pass attempts for 377 yards, three touchdowns and two interceptions before leaving the game late in the fourth quarter.

Purdy will undergo an MRI on Tuesday, but the belief is that he's dealing with a nerve issue while initial tests on his surgically-repaired UCL came back OK, per Matt Barrows of The Athletic. The quarterback was injured with just under two minutes remaining in the fourth quarter, when Lions defensive end Patrick O'Connor's hand and facemask landed on Purdy's elbow while safety Brian Branch brought Purdy to the ground for a sack. Backup Joshua Dobbs then came on to play the 49ers' final snaps of the loss while Purdy was seen getting his right arm checked out by team doctors on the sideline. With little at stake for the 49ers in their season finale Sunday in Arizona, Purdy could be a candidate to sit out, even if his injury isn't viewed as a major concern.
