Mark Buehrle also was cleared to make his scheduled start Friday after receiving an MRI on his sore back. ?He has nothing going on, just some muscular stuff,?? Schneider said. ?He has no bulging discs, no herniations. We can all rest comfortably. Plus, if he was going to sign another contract, they were going to want an MRI anyway. So, I killed about five birds with one stone.?? Buehrle has a $9.5 million club option for 2007, which the club is expected to pick up. They would owe the left-hander a $1 million buyout if they chose not to exercise his option.
