Cincinnati Bengals running back Chase Brown is in danger of missing his team’s Week 18 game against the Pittsburgh Steelers. After suffering an injury late in the prior week’s win to keep slim playoff hopes alive, Brown is trying to work his way back onto the field before kickoff — at one of the depth chart’s thinnest positions.

Cincinnati ruled Brown out of Saturday night’s regular-season finale against Pittsburgh with a sprained ankle. Brown, the Bengals’ leading rusher, did not practice all week after he got hurt during an overtime victory over Denver in Week 17.
