In an expected move, the NHL Players' Association filed a grievance on behalf of Keith Tkachuk Friday after he was suspended by the St. Louis Blues for failing a team physical.

NHLPA spokesman Jonathan Weatherdon said Monday that the grievance was filed on the same day as the suspension.

"We have disagreed with the suspension and are continuing to work at resolving it," Tkachuk's agent, Bob Murray, said Monday from Boston. "Hopefully we can find a quick and amicable resolution."

Blues' general manager Larry Pleau said Tkachuk is not welcome back until he passes the physical. "There's really not much to say other than he didn't pass the physical and he's suspended."

The 33-year-old left-winger had 33 goals and 38 assists for St. Louis in 2003-04.
