Running back Jerick McKinnon suffered a right-knee injury that required an MRI exam after Sunday’s practice.
But, as has been the case with other injuries that have mounted this training camp, the 49ers appear to have dodged a bullet.
McKinnon is “good” after tests revealed only a “muscle strain,” ESPN’s Adam Schefter reported about three hours after practice. The 49ers did not immediately confirm those results.
None of the 49ers’ camp injuries are believed to impact their status for the Sept. 9, regular-season opener. That includes cornerback Richard Sherman (hamstring), defensive linemen Arik Armstead (hamstring) and Solomon Thomas (concussion), tight end George Kittle (shoulder), guard Joshua Garnett (knee), nickel back K’Waun Williams (ankle), running back Matt Breida (shoulder) and linebackers Malcolm Smith (hamstring), Fred Warner (chest) and Brock Coyle (hip).
