It was in the second period of the fourth round-of-16 match against Minnesota that the accident occurred. In a melee at the goal, Lundkvist knocked over Minnesota's Michael McCarron, both fell to the ice and the Swede was hit in the face by his opponent's skate.
He went to the bench, left for the locker room and did not return to play.
"I don't know whether he was taken to the hospital, but we will examine him more closely when we return to Dallas," Gulutzan said.
Minnesota won the game 3–2 after overtime, tying the series at 2–2.
Lundkvist recently signed a new two-year contract with Dallas worth just over 32 million kronor.
