The Panthers' merry-go-round of injured players continued Friday as it has since training camp opened. Florida, which snapped its five-game losing streak Thursday, will likely have center Stephen Weiss back on the top line Sunday at Buffalo after he missed three games with a groin injury. Scottie Upshall, however, is going on injured reserve after he twisted his ankle while falling awkwardly during a fight in the third period Thursday. Upshall, who was helped off the ice, could be out for a month. He was seen at the team training facility on crutches. Upshall was hurt fighting James Wright — a winger who was waived by the Panthers during training camp and claimed by the Jets. "He twisted his ankle, it's pretty tender right now, so it's at least a few weeks perhaps a month away,'' coach Kevin Dineen said. Weiss' return is most welcomed as the Panthers will have their top line intact for the first time this season. "That gives you options,'' Dineen said. "It's not just the players you're missing, but the players we have are playing out of position to try and fit the square peg into the round hole.'' As Weiss and Tomas Fleischmann started the season, Kris Versteeg got hurt in the final practice of training camp. Versteeg returned Tuesday and scored his first goal Thursday. "I would love to come back and try and help out, for sure,'' Weiss said. "It's not totally up to me, but I got through practice and I'm going on the road. I'm looking to be back as soon as possible.'' Florida is currently without injured defensemen Ed Jovanovski (knee) and Erik Gudbranson (on rehab assignment in minors) as well as wingers Sean Bergenheim and Upshall.
