The Ravens think they'll have two key players on the field who are dealing with hamstring injuries today against the Browns.
Mitchell is an undrafted rookie who burst onto the scene last week with nine carries for 138 yards and a touchdown. Prior to last week he hadn't run the ball even once in his NFL career, but now he looks poised to be a big part of the Ravens' offense.
Humphrey's season had a delayed start because of a foot injury, but he has started the last five games.
The Ravens are 6.5-point favorites at home against the Browns.
