Jason Schmidt will have exploratory arthroscopic on his right shoulder tomorrow in Los Angeles, as doctors try to find out what exactly is wrong with it. Chad Billingsley will return to the rotation and take Schmidt's previously scheduled start on Thursday. Not only is his velocity down, but also he reported pain after his last start.

Yhency Brazoban has a torn labrum and will undergo surgery to repair his shoulder Friday. He is out a minimum of 6-8 weeks, and that's only if it's found that the tear is a small one. He would be lost for the season if the labrum was completely detached.

Ramon Martinez remained in Los Angeles to see a spine specialist and should resume baseball activities in a couple days.

James Loney is questionable for today's game and probable for tomorrow.

Chin-hui Tsao will throw again off a mound tomorrow and is nearing a return.
