#Ravens RB Mark Ingram, not spotted at practice by reporters on the scene, was essentially full speed last week on his calf. But he felt some tightness, source said, and pulled back to avoid re-injury. He still has a chance to play the #Titans on Saturday.

Mark Ingram practicing at full speed last week was a good sign that coaching staff wanted him to get reps ahead of the divisional round, but tightness in that calf could certainly mean a set back for the 30-year old. If Ingram's calf is reaggravated and he's unable to go, Gus Edwards and Justice Hill would share the backfield duties, but in a must-win situation for the Ravens, expect Ingram to give it a go on Saturday.

Harbaugh said that Lamar Jackson, Earl Thomas, Marshal Yanda and Brandon Williams all won't play Sunday against Steelers.

Ingram can likely be added to this list as Ian Rapoport already said Ingram won't play with his calf injury. It's a big blow to fantasy owners playing in the finals in Week 17 who now won't have Jackson as their QB. But with nothing to play for and having the top seed locked up, it's a good time to get Jackson some rest. Griffin gets the start.

RB Mark Ingram suffered what is believed to be a calf strain.

He'll have more tests today to determine the severity, Rapoport said. Rapoport added he left the stadium in a walking boot but that isn't always a big deal in terms of severity of the injury, and it just helps to relieve the pressure. Rapoport said Ingram won't play this week with nothing to play for, but it's not certain Ingram will be ready even after the bye week to open the playoffs.
