According to Peter Abraham of the Journal News, the Yankees have placed Mike Mussina and Carl Pavano on the disabled list. Both tried to work out today before the Yankees' game in Oakland, but neither made it very far.
Chris Britton has reportedly been called up from Triple-A, and now the Yankees will obviously need a starter for Tuesday's game against the Indians. Chase Wright is on the 40-man roster and in line to pitch on Tuesday. Steven Jackson was scheduled to start today for Triple-A Scranton/Wilkes-Barre, but that game was also rained out, so he too is a possibility. Tyler Clippard pitched for Scranton on Thursday, making Tuesday his next day to pitch.
I'll post more info once I find it out.
