According to MLive.com's Danny Knobler, Joel Zumaya will require surgery for a ruptured tendon in his right middle finger. He's been scheduled for a procedure on Thursday in New York, and doctors are estimating he'll be out for 12 weeks.

This news probably shouldn't be a surprise, as Knobler wrote earlier in the day. At the time a ruptured tendon hadn't been diagosed, but seemed likely. And if that was the case, a three-month recovery is pretty much the standard.
So what does this mean for the Tigers? I would think they'll try and hold the fort with the men they have, and maybe call up one of the hot arms from the minors. But I also can't imagine that Dave Dombrowski won't look into making a trade, as well. Middle relievers are a cherished commodity around the majors, but a few teams (Houston, Toronto, Philadelphia, Florida) have revolving closer situations and might be interested in a deal. Wishful thinking? Maybe, but at this point, it's worth indulging.
