Manager David Ross didn't disclose if Bryant would be available off the bench, but said he made the move out of "an abundance of caution."
Bryant was injured trying to make a diving catch in left field Wednesday in the fifth inning of the Cubs' 7-2 win at Cleveland. He remained in the game and hit a home run in the sixth inning before being pulled in the eighth.
"We're trying to be extra cautious," Ross said. "I don't think there's a great deal of concern. We just want to make sure he's good to go."
