Bates, who scored eight goals in seven games before going down,
was hurt in the final moments of New York's 5-2 victory at Florida
on Saturday night. The Islanders (11-10) went 3-1 on the trip and
have won four of five overall.
They return home to play Buffalo on Wednesday.
Bates, who scored two goals on Saturday, was injured in a hard
collision with Florida's Martin Gelinas near the Islanders bench.
The versatile two-way center, one of New York's top penalty
killers, has been bothered by groin injuries all season and missed
four games in October due to a troublesome hip.
He left the arena on crutches.
"It's a loss, no doubt," Islanders coach Steve Stirling said
Monday. "Shawn had been one of our best players of late. But every
team goes through injuries and it won't be an excuse for us. Shawn
played a lot, so this means opportunity for other players."
Bates has 10 goals, two assists and is a plus-2 in 17 games this
season. He scored twice in three of New York's last five games and
leads the NHL with a 35.7 shooting percentage.
To fill Bates' roster spot, the Islanders recalled 2003
second-round pick Jeremy Colliton from Bridgeport of the AHL.
Colliton, who had four goals and four assists in 18 games at
Bridgeport, is expected to make his NHL debut against Buffalo.
