Braves' Brandon McCarthy: To begin rehab assignment

McCarthy (knee) will start a rehab assignment at Triple-A Gwinnett on Saturday.

McCarthy will progress to the next step in his rehab after being placed on the DL in late June due to right knee tendinitis. The 35-year-old still believes that he'll be able to rejoin the fold at the major-league level this season, but in a bullpen role instead of the rotation.
