Ravens running back Justice Hill will miss Saturday’s game against the Pittsburgh Steelers due to a concussion.

Hill landed hard on his head as he fell over on the sideline at the end of a 25-yard run in the second quarter.

It was a frightening moment as Hill initially didn’t move as his teammates refrained from seeking medical attention. The game took place on the Ravens sideline and help was immediately there.

After a short break, Hill was back on his feet and went to the locker room. He was expelled shortly afterwards.

With Hill out and Keaton Mitchell inactive, the Ravens’ only two running backs for the remainder of the game are Derrick Henry and rookie Rasheen Ali.

Hill has been an extremely valuable part of the Ravens’ offense this season. He has 228 rushing yards and one rushing touchdown, but was even more valuable as a receiver, where he posted a career-high 42 catches for 383 yards and three touchdowns.

He was very dangerous in the Ravens’ screen game and a crucial part of the team’s pass defense.

With the Ravens playing the Houston Texans again in four days on Christmas, it could be difficult for Hill to be active for that game.
