During the Cincinnati Bengals' stunning 30-24 overtime victory over the Denver Broncos on Saturday, running back Chase Brown suffered an ankle sprain, according to head coach Zac Taylor, per NFL insider Tom Pelissero.

Brown suffered the injury while attempting to slide near the end zone late in the fourth quarter and the extent of the injury remains unknown at this time.

"I just know it's an ankle sprain, we'll see from there," Taylor told reporters post game.

Brown recorded 20 carries for 67 yards during Saturday's win before exiting the game just inside the two-minute warning of the fourth quarter and not returning to overtime.

After the injury, Brown managed to get back on his feet but took a few steps before collapsing to the turf. He then headed to the sideline with a noticeable limp.

Khalil Herbert stepped in to replace Brown, finishing the game with 23 yards on four carries.

In his second NFL season, Brown has logged 209 carries for 923 yards and seven touchdowns, appearing in all 14 games so far.

In his rookie season last year, Brown missed several games with a hamstring injury but still recorded 44 carries for 179 yards.

The Bengals' final game of the season against the Pittsburgh Steelers is a must-win for them to secure a postseason berth.
