CHICAGO -- Braves second baseman Marcus Giles was out of the lineup Saturday because of a concussion from colliding with Cubs pitcher Mark Prior, and both might not play in the All-Star Game.

They slammed into each other during Atlanta's 9-5 victory Friday, and Giles still had a headache Saturday. The Braves were planning to bring Dr. Joe Chandler of their medical staff to Chicago to examine Giles.

"If I'm not well enough to play in a regular season game, where it matters, the All-Star Game is just a bonus,'' Giles said.

He was chosen as the starting National League All-Star second baseman in fan voting.

Prior has a bruised right shoulder and was re-examined Saturday by a Cubs team doctor. He'll be checked again Sunday, and his status for the All-Star Game Tuesday in Chicago is in doubt.

"We have a few days to decide that. I'm sure he wants to pitch in the All-Star game, and we want him to pitch, but the most important thing is he is available for the second half,'' Cubs and NL All-Star manager Dusty Baker said.

The players were injured Friday in the second inning. Prior was running from first on a grounder hit to Giles, when the two slammed into each other on the basepath. Prior was called out for interference.

Prior's left knee hit Giles flush in the face. The Cubs' pitcher toppled over Giles, falling on his right shoulder.

Giles was woozy for several minutes after the collision and remembers very little.

"Everybody says I was up here (in the clubhouse) asking a bunch of questions, but I don't remember coming up here at all,'' Giles said. "I remember the siren of the ambulance, and I remember seeing my wife, and that's about it.''

Giles didn't blame Prior for the run-in.

"I was just trying to do what I normally do,'' he said. "It wasn't his fault, it wasn't my fault, either one. I hope he is OK and I'm sure he hopes I'm OK.''

Prior, an All-Star for the first time in just his second season, said he will abide by whatever Baker decides about the exhibition game.

"I wouldn't be upset. I think that is understandable,'' Prior said. "My job is for this team. If he thinks I shouldn't pitch to give me a couple of days off, that's fine. I would like to throw if I'm available.''

Prior said he still plans to be in uniform for the All-Star Game, even if he's not going to pitch.

"I want to be there and enjoy the experience,'' he said.
