Anderson was placed on the 15-day injured list Friday, retroactive to Sept. 5, with a right ankle contusion.
The right-hander was forced to leave Wednesday's game after a 103 mph comebacker off the bat of Jazz Chisholm caromed off his ankle. Anderson appears to have escaped with nothing more than a bruise, but it will still cost him at least a couple weeks and could perhaps end his season. Owen White was recalled in a corresponding move.
