Treanor has known the extent of the injury since Spring Training, but attempted to play through it. The Tigers called up Dane Sardinha from Triple-A Toledo, and he was in the lineup for Sunday's game agaisnt Kansas City.
"I tried everything I could to get through this," Treanor said. "It just didn't happen."
Treanor hopes that by having the surgery in the near future he'll be back for the latter part of the 2009 season.
"There are different timeframes, depending on the severity of it," Treanor said. "From what I've heard, two to three months."
Treanor had appeared in four games for the Tigers, going 0-for-13 at the plate. The surgery will be performed by Dr. Bryan Kelly of New York, who also did Chase Utley's surgery.
"[Saturday], I had my emotional day," Treanor said. "Now, it's time to move to the future. My ideal situation would be to get this taken care of and continue with the club in late July or August, maybe. I definitely want to be back at the end of the season. That's the goal."
Manager Jim Leyland said he feels bad for Treanor, but expressed confidence that Sardinha can handle the backup catcher role behind starter Gerald Laird.
"I really like Sardinha," Leyland said. "He's an excellent catcher. We don't expect a lot of offense from him. I'm not sure anybody expects a lot of offense from their backup catcher. "The bad part isn't having Sardinha here. It's that you feel sad for Treanor. Matt is a tough kid and tried to play through it."
Sardinha hit .231 in five games at Toledo before getting the call to join the Tigers in Kansas City. Treanor, who was signed by the Tigers as a free agent last December, is in his 16th year in professional baseball. He played five years for the Marlins and had a career-high 206 at-bats in 2008.
