CLEVELAND -- LeBron James winced with pain at times during practice Wednesday, a day after he woke up with a strained chest muscle.

James sat out the Cleveland Cavaliers' exhibition game Tuesday night against Boston and is listed as questionable with a strained left pectoral muscle for Friday night's home exhibition game against Philadelphia.

He began experiencing pain Tuesday. But he was baffled about how he was injured in an exhibition game Monday night against Washington.

"I don't know where it came from," James said. "I don't remember getting elbowed in the chest. I woke up yesterday morning and it was hurting. It's something I've never felt before."

He said he wouldn't have been able to play Tuesday night even if it had been a regular-season game.

"I'm not 100 percent right now, but I'm getting there," he said.
