Philadelphia Flyers forward Scottie Upshall will likely be sidelined for six weeks because of a broken wrist.
Upshall, 23, suffered the injury during Tuesday's 4-2 exhibition loss at Ottawa, the same contest that prospect Steven Downie was suspended indefinitely for a violent hit on Senators forward Dean McAmmond.
The Flyers also lost forward R.J. Umberger for two weeks with a broken pinky finger on his left hand.
Both he and Upshall underwent surgery on Thursday, while newcomer Joffrey Lupul received treatment for a sprained left wrist.
"He had some medicine injected into that wrist this morning and we are hopeful that, with three-to-five days of rest, he will be better," Flyers general manager Paul Holmgren said of Lupul, who was traded July 1 to Philadelphia by the Edmonton Oilers.
Upshall has posted eight goals and eight assists for 16 points in 32 games for the Flyers, who acquired him last Feb. 15 from the Nashville Predators, along with Ryan Parent and two draft picks, for Peter Forsberg.
Upshall, from Fort McMurray, Alta., has racked up 17 goals and 42 points in 95 NHL games since being drafted sixth overall by Nashville in 2002.
Umberger, who is entering his third NHL season, has 36 goals and 66 points in 154 games with the Flyers.
The 25-year-old Pittsburgh native was drafted 16th overall by the Vancouver Canucks in 2001, but signed a free-agent contract with Philadelphia on June 16, 2004.
