McCann had to have his knee drained on May 28th after barely finishing the Astros win against the Yankees. With McCann 34 years old, there has to be more caution with these issues.
During his recovery, Max Stassi will take the full-time catcher position. AAA player Tim Federowicz has been called up to the main roster.
McCann has 5 HR's and 17 RBI's on the season.
