Flyers winger Scott Hartnell had  an elevated heart rate after the second period of the team's 3-1 win in Detroit on Friday and will see a cardiollogist Tuesday, GM Paul Holmgren said after Sunday's practice in Voorhees.

Hartnell's heart rate has since gone down, Holmgren said, but the Flyers did not want to take any chances.

The veteran winger will sit out Monday's exhibition against the Rangers as a precaution. He did not play in the third period on Friday.

According to, the heart may start beating faster for several reasons, including exercise and exertion, dehydration, stress, an anxiety or panic attack, fear, anger, blood-sugar fluctuation, excessive caffeine consumption, or as a reaction to or side effect of taking certain medications.

Holmgren and coach Peter Laviolette both used the word "scary" to describe what happened Friday.

Before Holmgren addressed the media, Hartnell had downplayed the reason he had missed practice on Sunday and never revealed the heart problem.

"Just a maintenance day, just a little sore," he said. "Soreness everywhere. First couple weeks of the season  everyone is having a tweaked muscle here and there and it's better to be safe than sorry."

The Flyers released veteran forwards Michael Nylander and Adam Mair from tryout contracts on Sunday, Holmgren announced.

Counting players placed on waivers and two injured prospects, the Flyers have 29 players left in camp. They figure to open the season with 22.

Because of injuries, Nylander never played any games in camp. Mair played one game.

The Flyers obviously want to take a longer look at young prospects like Sean Couturier, Brayden Schenn, Matt Read, Zac Rinaldo and Tom Sestito, among others.
