Dominick Puni

49ers G Dominick Puni (shoulder) is undergoing an MRI on Monday.

The rookie guard played every snap in Week 12’s loss to the Packers, but apparently something popped up. He’d be a huge loss for the 49ers. Deommodore Lenoir (knee) is also getting an MRI for the 49ers after playing 93 percent of the snaps. This team just can’t buy a health-based break this year.
