"If I can move around and I can block [pitches in the dirt], I'm going to play, for sure," McCann said.
McCann exited Saturday's 2-0 loss to the Nationals after being hit just above the left knee with a Jonny Venters pitch in the seventh inning. The six-time All-Star catcher appeared to get crossed up on the pitch. After the pitch went into a camera well next to the home dugout, the Nationals had runners on second and third with one out.
"I'm going to get here with the intention to play [Sunday], and go from there," McCann said. "I came out of the game there because I couldn't really go down on my knees to block. That's a big situation there."
After feeling discomfort as he attempted to crouch with manager Fredi Gonzalez and trainer Jeff Porter by his side, McCann limped off the field under his own power. He was replaced by David Ross, who made his first appearance since slightly tweaking his right groin during the opener of last weekend's series against the Nationals.
"It was nice that Rossy was able to come out of that game OK," Gonzalez said.
Ross would be available to start Sunday's game, if necessary, and the Braves are still carrying a third catcher, J.C. Boscan.
