From RussianHockeyFans.net, which has been doing some nice coverage lately of the KHL:
According to a Russian site lifesports.ru during the second period a Vityaz forward ran into Gerber. As a result Gerber ended up lying on the ice. After being tested by the team's doctors Gerber was put on a wheel stretcher and taken off the ice. He was sent to a Podolsk municipal hospital where he was diagnosed with a compression fracture of the third cervical vertebra.
According to Sovietsky Sport, the injury was a "fracture of the fourth cervical vertebra," but that was a preliminary diagnosis. Gerber was also motionless for a while before being stretchered off (photo and story from SovSport here). He's due for more evaluation on Monday.
