In a must-win game for the Pittsburgh Steelers, their star linebacker left the game with an injury.
Pittsburgh's TJ Watt injured his knee in the second half of Saturday's game against the Ravens, was examined in a blue medical tent and headed to the locker room, but was not cleared for the remainder of the game.
In the third quarter, Baltimore quarterback Tyler Huntley threw a pass to his right, but it was knocked down by Steelers tackle Montravius Adams.
But when Adams knocked the ball down, the momentum sent it flying toward Watt, striking what appeared to be the linebacker's left knee.

Watt lay on the ground and was eventually helped by training staff and walked to the locker room on his own.
Before his injury, Watt was putting up gaudy numbers with eight tackles and two sacks a game as the Steelers looked to earn a postseason berth.
Watt would finish the regular season with 19 sacks, 68 tackles and one interception.
He was named to the Pro Bowl earlier this week.
