"It's not a good day for a rest," McCann said before Saturday's game against the Dodgers. "I'd like to be playing."
Gonzalez informed McCann on Friday that he would not be in the lineup for the first two games of this weekend's series.
When asked to explain this decision, Gonzalez made it clear that the shoulder was not an issue. The decision seemed to have more to do with the recent struggles of McCann and the fact that David Ross entered the game with four hits, including three home runs, in nine at-bats against Dodgers scheduled Saturday starter Aaron Harang.
"[The shoulder is] not 100 percent, but who is 100 percent at this time of the year?" Gonzalez said. "He'll be in there tomorrow."
After McCann received a cortisone shot that forced him to miss two games last week, the Braves revealed that he was dealing with a right shoulder subluxation. McCann made it known that he does not agree with this diagnosis.
Instead, McCann believes his shoulder discomfort is a product of a cyst and a frayed labrum. An MRI exam performed a couple months ago led to this diagnosis.
"I've got a cyst that is sitting on a joint and a frayed labrum," McCann said. "I've got things going on in there. But it's something I'm managing. I'm going to play through it, and at the end of the year, I'm going to see what I have to do."
McCann has battled some shoulder discomfort most of this season. It appeared he had turned a corner when he batted .308 with nine home runs and a 1.115 OPS in the last 18 games he played in July. But he has been limited to four hits, all singles, during his first 36 at-bats in August.
"I can pinch-hit," McCann said. "I can play. I can do all of the things that I need to do to play."
