(CBS) The Cubs’ outfield will have a markedly different look for a bit.

On the day Chicago demoted outfielder Kyle Schwarber to Triple-A Iowa, it also placed outfielder Jason Heyward on the 10-day disabled list amid a series of roster moves. Heyward has a left hand abrasion, and the move is retroactive to Monday.

In corresponding moves, the Cubs called up right-hander Dylan Floro and outfielder Mark Zagunis from Triple-A. Zagunis had to be added to the 40-man roster, so left-handed reliever Zac Rosscup was designated for assignment.

Heyward is hitting .258 with six homers and 29 RBIs in 55 games.
