MIAMI -- Braves All-Star catcher Brian McCann is expected to begin his Minor League rehab assignment with Triple-A Gwinnett on Friday. McCann will play at least two games and possibly three before being activated from the disabled list.

It is unknown whether McCann will play catcher during each of the games of his rehab assignment. With the Pawtucket Red Sox, an American League affiliate, in town this weekend, Gwinnett will be utilizing a designated hitter, and there is a chance McCann could fill that role for at least one game.

McCann has been sidelined since straining his left oblique muscle on July 26. There is a chance the six-time All-Star catcher will return in time for Monday's series opener against the defending World Series champion Giants.

Braves hope Hanson will be ready for next start

MIAMI -- There is certainly some reason to be concerned by the fact Tommy Hanson's right shoulder is bothering him for the second time in a two-month span. But the Braves received some encouraging news when results of Tuesday's MRI exam showed no structural damage to Hanson's shoulder.

Hanson received a cortisone shot after members of the Braves' medical staff determined his discomfort is being caused by tendinitis. This was the same diagnosis the 24-year-old right-hander received when he also received a cortisone shot and missed two weeks while on the disabled list in June.

Braves manager Fredi Gonzalez said he is still hoping Hanson will be able to make his scheduled start Tuesday against the Giants. He would be making the start on nine days' rest.

After allowing seven runs and four homers against the Mets last Saturday, Hanson indicated that his right shoulder has been bothering him. He admitted it to Gonzalez the following day.

During his first 17 starts this season, Hanson posted a 2.44 ERA and limited opponents to a .190 batting average. In his five starts since the All-Star break, he has posted an 8.10 ERA and opponents have hit .313.
