According to the Denver Post, the 27-year-old Swiss international had to leave the ice with what seems to be a head or neck injury and after further evaluation did not return to play. He was replaced by emergency call-up Calvin Pickard, who made his NHL debut tonight.
UPDATE Because of his neck injury, Reto Berra is doubtful for Saturday's road game against the Montréal Canadiens. This is what Mike Chambers of the Denver Post reports on Twitter. - 17 October 2014, 8:41 PM
