ANAHEIM -- On the day catcher Mike Napoli and shortstop Maicer Izturis returned to the starting lineup after injuries, the Angels had to deal with another injury as outfielder Reggie Willits was placed on the 15-day disabled list because of a concussion he suffered Friday night.

Willits, who suffered a concussion Sunday at Yankee Stadium when he collided with Gary Matthews Jr. in right-center field, suffered his second concussion in six days when he was tagged in the head by Yankees pitcher Brian Bruney while sliding headfirst into home in the seventh inning on Friday.

"I think it's extremely bad luck," Willits said. "It's the only way to describe it. If he hit in the other side of my head, I don't think it would have happened, but he hit me on the same side I hurt in New York."

His move to the disabled list was precautionary because of the dangers of suffering a third concussion and missing possibly the entire season.

"I think it's a different kind of injury because you know you can go out and play and feel normal," Willits said. "They told me there's 10 days where you can reinjure it. I think at this point in the season, they're being extremely cautious not to put myself in a situation where I could get a third one."

Angels manager Mike Scioscia echoed his fears about the possibility of Willits sustaining a third head injury.

"The fact that it happened again, they just want to make sure everything checks out," Scioscia said. "So there's a concern there that if it happened again right now, he could be out for a long time."

Sean Rodriguez, who was hitting .306 with 21 home runs and 52 RBIs in 66 games with Triple-A Salt Lake, was recalled to take Willits' roster spot.

"Sean's versatility is important," Scioscia said. "He can play all three outfield positions along with the middle infield, so with Izzy's thumb still progressing, it gives us a guy who's multidimensional."

Because Willits' injury happened late Friday night, Rodriguez had to fly out early Saturday morning and was operating on very little sleep.

"I'm a little tired right now, to be honest," Rodriguez said. "I didn't find out I was coming back until around midnight last night. I had to go to the field in Salt Lake this morning and pick up my baseball stuff before I got my flight. So it's been a little hectic. But I'm really happy to be here. This is where I want to be. I had a great time when I was up here last time."

Rodriguez batted .185 with one homer and three RBIs in 22 games with the Angels this season when second baseman Howie Kendrick was on the disabled list in May.
