'Great Attitude and Demeanor!' Ravens RB Keaton Mitchell After 'Heartbreaking' Injury

"I was just in there and we were talking," Harbaugh said. "He's just got a great attitude and demeanor about him. It's a guy that you want to see do well. He deserves to do well."

Mitchell was undrafted and signed by the Ravens in the offseason. His father, Anthony, played for the Ravens and won a Super Bowl for Baltimore.

In the last six weeks, Mitchell has been hot, rushing for 480 yards and two touchdowns. The team will now have to replace those numbers with heavier doses of Justice Hill and Gus Edwards, who have combined for 976 yards and 14 touchdowns this season.

Part of that No. 1 rushing attack is quarterback Lamar Jackson, and he'll have to continue to be a big part of the ground game as the Ravens prepare for the San Francisco 49ers in Week 16 - Baltimore's biggest test yet. The 49ers allow the third-least ground yards per game at 89.4.

The Ravens still hold the AFC's No. 1 seed in their collective hands. But they'll have to take care of the 49ers, Dolphins, and Steelers to end the regular season.
