Alex Avila was held out of the starting lineup this afternoon against the White Sox after he hurt his jaw in a collision with teammate Prince Fielder during yesterday’s game, but the hope was that he wouldn’t have to miss much time after he passed a concussion test. However, Tigers manager Jim Leyland told Chris Iott of MLive.com after today’s game that Avila had a headache during batting practice and won’t return to the lineup until he’s back to 100 percent.

“He wasn’t going to play under any circumstances,” Tigers manager Jim Leyland said after his team’s 5-4 loss to the Chicago White Sox. “And I can’t tell you about tomorrow. That’s a real touchy one when you start messing with upstairs. I’ll have to feel 100 percent that he’s totally cleared before I play him.”

It’s not clear if Avila will be sent for more tests, but obviously the Tigers aren’t going to take any chances if the headaches continue. Gerald Laird started behind the plate this afternoon and went 1-for-3 with a run scored. Bryan Holaday, a September call-up, is the third catcher on the active roster.

Avila, 25, is batting .247/.355/.388 with eight home runs, 43 RBI and a .743 OPS in 107 games played this year. He has thrown out 31 percent (33 out 106) of attempted basestealers.
