Partly as punishment for the nine penalties they committed Tuesday, new Flyers coach Peter Laviolette put his players through a tough practice Wednesday that included extra skating drills.

Laviolette said he wants the players to be accountable for their actions.

The Flyers, coming off a 6-2 win over the Islanders, host Ottawa Thursday.

Goalie Ray Emery had successful abdominal surgery Wednesday and is still expected to miss six weeks, GM Paul Holmgren said.

According to Holmgren, Dr. William Meyers repaired "a significant tear of his rectus abdominus on the left side of his lower stomach." The operation was performed at Hahnemann University Hospital.

Emery will  be released later Wednesday and initiate his rehab Thursday, the GM said.

Brian Boucher (2.53 GAA, .903 save percentage) has become the Flyers' No. 1 goalie _ and said he is excited by the challenge.
