Phils general manager Ruben Amaro Jr. said a Sunday MRI exam revealed only a Grade 1 contusion for Polanco. The 34-year-old is scheduled to fly to Philadelphia to get a cortisone shot on Monday morning, and he will be available to play on Tuesday or Wednesday against the Braves, Amaro added.
Polanco, out of the starting lineup for the third consecutive game on Sunday against the Marlins, originally suffered the injury after being hit by a Tim Hudson fastball on April 21. Polanco aggravated it while stretching out for a line drive on Thursday against the Mets.
But tests revealed no bone chips -- just a bone spur Polanco has had for years -- and just a bit of a bruise above the left elbow.
"He's got just a little bit of a muscle contusion and some bone bruising," Amaro said. "No structural damage. He's going to probably have a cortisone shot to calm it down and should be available Tuesday or Wednesday."
Polanco is batting .306 with five homers and 21 RBIs in 44 games this season. In his absence, Juan Castro has been starting at third base, and shortstop Wilson Valdez has hit in Polanco's usual No. 2 spot.
