Primeau told The Philadelphia Daily News on Monday that he was not where he wants to be in his recovery from a concussion.
Primeau has been out of the lineup since Oct. 30. He took an elbow to the jaw a few days before that date, saying he felt fine after the hit. But he then began having persistent headaches and weariness and was pulled ultimately from the lineup.
Flyers GM Bob Clarke told the newspaper that Primeau and Eric Desjardins (also suffering from a concussion) both passed "baseline neurological tests" Monday, but there is no set date for either player's return.
"I continue to make progress, but it's been slow, and it's frustrating," Primeau told the Daily News on Monday. "It seems to heal on a pace all its own. The last one I had, I thought if I take a week to relax, kick my heels up, I would feel good.
"It turned out being eight weeks. I thought when this happened, it would be a week. That has not been the case, and it's coming up on three weeks now."
Primeau also squashed rumors that he might retire.
"Glad to see people are planning my retirement for me," he told the newspaper. "Not going to happen."
Primeau missed 21 games during the 2003-04 season after a concussion and suffered two more head-related injuries in the playoffs. He has one goal and six assists in nine games for the Flyers this season.
