Teahen rejoins Royals, available to play

Lower back tightness turns out to be only muscle spasms

DETROIT -- Third baseman/outfielder Mark Teahen rejoined the Royals for Tuesday night's game after traveling to Kansas City for an evaluation of lower back tightness.

He wasn't in the starting lineup against the Tigers but was available to play.

"It was just muscle spasms, so it was a positive report for us," manager Trey Hillman said. "He's available, but he's going to stay inside [during batting practice] and do some work today. We've got him available for the game if we need him."

Teahen left the club before Sunday's game at Cleveland.

"It just kind of tightened up on me before that Saturday game when I was taking ground balls like normal," Teahen said. "So I just went and made sure there was nothing crazy wrong with it, which there wasn't."

The back felt much looser on Tuesday, he said.

"I've had issues with my back in the past and it's something I've just got to continually stay on," Teahen said. "I'm available. I'm sure we'll try to be smart with it, but I can do more or less whatever."
