Petry (ribs) indicated the he felt better Thursday after leaving Wednesday's game against the Bruins with the injury, Jim Matheson of the Edmonton Journal reports.The blueliner hopes to be available for the Oilers' next game Friday against the Wild, though his status likely won't be determined until earlier that morning. Even if Petry ends up missing the game, it appears he's not looking at any sort of lengthy absence. That's something of a relief for the Oilers, who are believed to be interesting in trading Petry prior to the Mar. 2 deadline.
