Contreras will catch Saturday's game against the Pirates, Jesse Rogers of ESPN Chicago reports.
David Ross was placed on the 7-day disabled list due to a concussion Wednesday, so Contreras will move back behind the plate Saturday to catch for Jon Lester. Contreras has been moved around the diamond since coming up to the Cubs, making 11 starts behind the plate to go with seven appearances in left field and two appearances at first base. Not only has Contreras' versatility been valuable thus far, but he's been tremendous at the plate as well. He's slashing .300/.391/.617 with five home runs in his first 60 big league at-bats.
