THRASHERS: The collapse of goalie Ondrej Pavelec in the season opener turned out to be a fainting spell.
The Thrashers said Monday that preliminary tests on Pavelec showed he had a kind of episode that is described on the Mayo Clinic Web site as the most common cause of fainting, but he will undergo more tests as a precaution. Pavelec's worst injury was the concussion he received when he fell backward after fainting.
If tests come back negative, he will be cleared to play once he gets over his concussion symptoms, which include a headache.
