C. Davis could be done for season; Klein has procedure; lineup, Machado ejected (updated)
Orioles first baseman Chris Davis is headed to the disabled list to make room for tonight's starter, Brian Matusz, on the active roster.
Orioles president of baseball operations Andy MacPhail said Davis has a small tear in his right shoulder. He'll see renowned orthopedist Dr. Lewis Yocum on Thursday and could miss the rest of the season.
In other injury news, Orioles pitching prospect Dan Klein had an anchor put in Tuesday to repair a slight labrum tear in his right shoulder and his shoulder capsule loosened.
The reliever, 23, will start throwing program in mid-December. He won't be ready for start of next season but should be able to pitch during the 2012 season.
The most realistic case for Klein is probably his pitching in games in late May or June. It's decent news for the Orioles, who feared worse for their 2010 third-round pick.
UPDATE: Before you ask, Orioles top prospect Manny Machado was not injured tonight. The Single-A Frederick shortstop was ejected from the game for slamming his helmet.
