"The doctors will be looking at him," Phoenix coach Dave Tippett said Sunday after a 4-2 win that gave his team a 2-1 series lead. "We'll see where he's at (Monday)."
Doan collided with Detroit goaltender Jimmy Howard on his first shift of the second period, lost his balance and ran into the endboards. He later walked toward the dressing room and didn't come back.
The Coyotes did not disclosed what he injured.
Doan had a goal and an assist during the first two games, which were split in Phoenix. He led the Coyotes with 55 points during the regular season.
