Votto had a piece of loose cartilage removed from his surgically repaired knee on Friday back in Cincinnati and is expected to be out an additional seven to 10 days from his original expected return date of sometime next week.
Rolen's ailment is a different story. The veteran third baseman said his lower back started giving him trouble toward the end of a three-game series in Milwaukee to start this road trip. He missed the final game of that series and the first three games of the series against the Cubs at Wrigley Field, including Saturday's game.
"It's better than [it was Thursday]," Rolen said after Friday's 10-8 win against the Cubs. "I'm not moving too good yet."
Rolen is listed as day to day, but said he's gone through this before and hopes it will clear up relatively soon.
"I know it's not feeling good [right now], but my history's been ... if it's like it's been before, [it should take] a week, or less than a week," Rolen said.
