Hall was falling forward after a cross-check from P.K. Subban in front of the Devils' net when a slap shot from teammate Colin Miller struck him in the face. He was able to skate off under his own power but went immediately to the dressing room.
Hall re-joined his teammates on the ice to start the second period.
While the 29-year-old appears to have avoided serious injury, the incident still comes at a time where the Sabres are stuck in an 11-game losing streak and comes one day after the team lost 6-0 to the Washington Capitals. Hall, who signed a one-year, $8 million contract in free agency, has struggled through the first half of the season, only scoring two goals and 16 points through 27 games.
