Jerick McKinnon injury update: 49ers running back (knee) has another setback, GM John Lynch says

Jerick Mckinnon injury update: Starting season on IR 'an option' for 49ers running back

Jerick McKinnon’s surgically repaired knee has made it difficult for him to be fully engaged in practice.

General manager John Lynch revealed the running back suffered another setback during his recovery.

“Yesterday (Tuesday), we brought him out, and it’s a real bummer because he keeps getting to the final step. And the final step is actually playing NFL football, particularly at his position where you’ve got to make hard cuts, you’ve got to put your foot in the ground,” Lynch said (via

“We did it a month ago, and we got to that step, and he kind of regressed. And I would say yesterday, we had a similar situation. So we’re trying to get to really what’s the root cause of the problems that he’s having.”

The team described the knee issue as a “flare up,” according to NFL Network

“Just because he’s kind of working through this, we’re working it, I’m going to kind of leave it at that, but yesterday was not encouraging from that standpoint,” Lynch added. “What that means, we’re not sure yet, and we’re working hard to find that out.”

McKinnon signed a four-year, $30 million contract with San Francisco in March 2018, but did not appear in a game last season after he tore his ACL in early September. The 49ers activated McKinnon from the PUP list earlier this month.

The 49ers also have running backs Matt Breida and Tevin Coleman on their roster, and they could help fill the void if McKinnon misses more time this season.
