Cameron Maybin is dealing with an injury to the right side of his rib cage.
A rib popped out and had to be put back in place, per George Sipple of the Detroit Free Press. That explains why Maybin has been absent from the Tigers' starting lineup for the last three games. He did say he's feeling better Tuesday and this doesn't sound like it's going to be a disabled list situation.
Joe Ross (shoulder) will throw a bullpen session Wednesday in Cleveland.
Ross joined up with the Nationals on Tuesday after going three scoreless innings in his rehab debut Sunday with Low-A Hagerstown. He only threw 43 pitches in that outing, so another rehab appearance is likely in the plans. The right-hander might even need two more minor league starts.

Get the 25-year-old southpaw activated in all standard fantasy leagues.
