PHOENIX -- Jose Contreras' strained right forearm was examined by team doctor Michael Ciccotti in Philadelphia on Monday and the Phillies' closer is scheduled for an MRI on Tuesday.
General manager Ruben Amaro Jr. said the results of Monday's exam were "more positive" than the first one on the 39-year-old right-hander in San Diego.
Contreras had been closing for Brad Lidge, who has been out since spring training with a strained rotator cuff and hopes to be back after the All-Star break.
Contreras had five saves in five tries and had not allowed a run in eight innings this season. Ryan Madson has taken over since Contreras was hurt.
Phillies manager Charlie Manuel bristled when asked if Contreras had been overused at the outset of the season.
"I feel like, first of all, that there's no way in hell we overused Contreras," Manuel told Philly.com. "That's how I feel. There's no way. What did he pitch? The most games was three. Then he had a day off. He pitched five times in seven days. We weren't trying to stay away from him. He was closing games for us. That's how I look at it."
Philadelphia purchased the contract of right-hander Michael Stutes from Triple-A Lehigh Valley.
