"I'd probably be playing right now if that had gone well," Madson said.
On Thursday, Madson -- who spent the past week in Arizona getting treatment -- planned to play catch prior to the game against the Orioles.
"It feels better now, but that could just be the non-throwing," Madson said.
Madson did not throw a baseball while he was in Arizona, but used his time there to get the scar tissue removed from his elbow.
Scar tissue is a regular part of the recovery from Tommy John surgery. It usually tears off while a pitcher is throwing and rehabbing, but that never happened with Madson, so the tissue was manually removed.
