The Orioles have announced that right-hander Jason Hammel, who left Friday’s game in the fourth inning when he re-injured his balky right knee, will miss his next start, which was scheduled for Wednesday in Minnesota.

Hammel had a MRI on Saturday afternoon, but the results were not immediately announced. However, the club said Hammel would miss one start. Orioles manager Buck Showalter is expected to address the situation and Hammel’s treatment options after today’s game against the Detroit Tigers.

Hammel, who is 8-6 with a 3.54 ERA in 18 starts, has been bothered by the knee since early May, but has attempted to pitch through it.

The best guess right now is that lefty Brian Matusz, who was sent to Triple-A Norfolk on July 1, will return to make that start. Matusz was 5-10 with a 5.42 ERA in 16 starts with the Orioles this season. He was scheduled to pitch for the Tides on Sunday.
