McCann to play at Triple-A on Thursday

Catcher will suit up for Gwinnett before rejoining Braves

ATLANTA -- Brian McCann's new prescription glasses showed up a day early and without all of the necessary parts. Thus the All-Star catcher will now limit his Minor League rehab assignment with Triple-A Gwinnett to Thursday's game against Syracuse.

After opening the box that arrived on Tuesday night, McCann found his prescription Oakleys without the right lens. It's expected to arrive by Thursday morning.

The Braves' catcher had been under the impression that he wouldn't even receive the glasses until Wednesday afternoon.

McCann, who will serve as Gwinnett's catcher on Thursday, has been bothered by blurred vision in his left eye since Opening Day. Because contacts provided discomfort, he has now decided that wearing glasses is the best way for him to remedy the slight vision change that he's experienced since undergoing Lasik surgery after the 2007 season.

To account for the presence of the glasses, McCann will wear a hockey-style catcher's mask. He was pleased with the comfort it provided while he wore it during the throwing exercises that he performed at Turner Field on Tuesday afternoon.
