San Francisco left tackle Joe Staley was injured late in the third quarter with the 49ers enjoying a comfortable lead at the Cincinnati Bengals on Sunday.
Staley, a six-time Pro Bowl selection, went down on a run play to his side and limped to the sideline, where he received treatment on his left leg. He was taken off the field on a golf cart for further evaluation.
The 49ers were up 34-10 at the time.
Staley, 35, has started all 176 games of his NFL career with the 49ers, who selected him with the 28th overall pick in the 2007 draft. He started all 16 games last season for the first time since 2015, allowing 3.5 sacks, per STATS LLC. That was his lowest single-season figure since 2013.
The team signed Staley to a two-year contract extension this summer, putting him under control through the 2021 season.
