LOS ANGELES — Glen Davis raised a few eyebrows when he was spotted wearing ear plugs during Game 1 of the NBA finals.

But it wasn’t to block out the jeers of the Lakers fans sitting behind the Celtics bench — “Fans are fans … Everyone feels like they can joke on me,” he said before practice on Friday. It was to block out loud noises, a cause of aggravation since suffering a concussion in the Eastern Conference semifinals.

The earplugs worked. Well, after Davis made a minor adjustment.

“You know what’s so funny?” he said. “I didn’t think they worked well at first, but then Rasheed (Wallace) was like, ‘Turn them around,” because I had them stuck in my ear the wrong way.”

Davis removed the ear plugs when he played, but said he gets into a zone on the court and doesn’t hear the noise anyways. But he never misses Doc Rivers calling for him to get in the game.

“You can always hear him – ‘Baby! Baby!’” Davis said, channeling an impression of his coach. “He’s loud, so I can hear him. I’m always looking at him anyways because he’s always standing up that way because the game’s that way.”
