Kyle Schwarber has turned into one of the most important hitters for the Cubs, but manager Joe Maddon won't be writing the rookie's name on the lineup card for a few days.
Schwarber will sit out the next three-to-five days with a strained right rib cage suffered on a check swing during warm-ups in the batting cage prior to Wednesday afternoon's game. He was taken out of the lineup that day and went for an MRI.

Schwarber will not play at all this weekend against the Arizona Diamondbacks at Wrigley Field, with new acquisition Austin Jackson instead in the lineup Friday afternoon, playing right field (and pushing Chris Coghlan to left) and hitting second.
