Braves catcher Brian McCann left Tuesday's game against the Pirates with a strained left oblique. He will be placed on the 15-day disabled list on Wednesday.

The Braves said they will announce the corresponding roster move on Wednesday. Following the game, Braves manager Fredi Gonzalez said he expected J.C. Boscan to be called up from Triple-A Gwinnett.

"Hopefully it is not a bad oblique," Gonzalez said. "There are different grades of it and hopefully we can get him back in 15-20 days. That's a big bat out of the lineup."
