KISSIMMEE, Fla. -- Braves backup catcher David Ross left Tuesday night's game against the Astros with a strained right groin. His status for the start of the season will be better known after he is further evaluated on Wednesday.

Ross suffered the strain at the conclusion of the fifth inning as he was running to first base after hitting a fly ball to center field. After showing initial signs of discomfort, he made his way back to the dugout on his own power and was immediately removed from the game.

Ross, who has hit .175 with three homers during the Grapefruit League season, signed a two-year, $3 million deal in December to serve as All-Star catcher Brian McCann's backup. If he's not ready to start the season, Clint Sammons will likely be recalled from the Triple-A Gwinnett roster.

McCann has dealt with his own aches and pains this week. He bruised his right ring finger courtesy of a foul tip on Saturday and then suffered another bruise above his right knee when he was struck with a foul ball during Monday afternoon's game against the Red Sox. He's expected to return to the lineup on Wednesday.
