Montas was placed on the 7-day DL at Triple-A Oklahoma City, retroactive to June 17, Eric Stephen of SB Nation reports.
According to Andy McCullough of the Los Angeles Times, Montas is dealing with irritation in the area of his rib surgery incision. It's undoubtedly a frustrating setback for Montas, as he had put himself into position to claim a spot in the major league rotation, but this issue is not believed to be serious. The Dodgers appear set to go with a four-man rotation this week with an off day Thursday and Carlos Frias sent down.
