Okuayinonu suffered an apparent ankle injury during the 49ers' training camp practice Wednesday, Matt Barrows of The Athletic reports.
The severity of the issue is still unknown at this point, but Okuayinonu's is one of more than a few injuries San Francisco now has to contend with on its front seven. Until Okuayinonu is back on the field, veteran Ogbo Okoronkwo could see an uptick in practice reps on the edge.
