WFAN is reporting that Joba Chamberlain will be placed on the 15-day disabled list and Chris Britton will be called up, as he is headed for Texas for tonight's game. No news so far on exactly how Chamberlain's visit with Dr. Andrew went, but we now know that he will be missing three starts at least.

Britton will be called up to take his place on the roster, who will also be sent down and then be called back up and sent back down again all within the next three hours.

Also of note: As of the time of this post (about 5:30 P.M. ET), Jeff Karstens is perfect through seven against Randy Johnson and the Diamondbacks.

UPDATE: Karstens just allowed a double in the bottom of the 8th with two outs, so his perfect game ends just four outs short. Karstens has not allowed a run in two starts since the Yankees unloaded him.

Yikes.
