The Athletic’s Matt Barrows reports that 49ers WR Christian Kirk “walked off with a trainer midway through the session” on Sunday.
Kirk, 29, is entering his ninth NFL season. As is often the case with NFL veterans, Kirk has picked up his fair share of injuries over the years, including two hamstring strains last season. Fortunately, we are a long way from Week 1. There is no cause for concern at this time. 49ers acting head coach Chris Foerster will address the media shortly, so we could have clarity as to what the issue is soon.
