"Hopefully, this will get him over the hump," Braves manager Fredi Gonzalez said. "You just have to give it a couple days for the cortisone to work. He's fine."
McCann has spent the past couple of months experiencing some discomfort whenever he extends too far while swinging a bat. The ailment has not affected him when throwing the baseball.
"I've been feeling it for a while, but it's gotten worse over the past two weeks," McCann said. "I just want to get it to not affect my swing."
McCann hit .296 with nine home runs and a 1.059 OPS while playing 20 games in July. He has recorded three hits in his first 15 at-bats this month.
