Chacin was placed on the 10-day injured list, retroactive to July 24, with toe sesamoiditis, Danielle Allentuck of The Denver Gazette reports.
Chacin last pitched Saturday in Milwaukee and surrendered two runs over 1.2 innings, and he'll now be sidelined for at least the next couple weeks with a toe issue. Justin Lawrence was recalled from Triple-A Albuquerque in the corresponding move.
