Nilsson's mask fails to withstand Ristolainen slapper

Friendly fire.

Buffalo Sabres netminder Anders Nilsson had to resort to the stock, white mask after defenseman Rasmus Ristolainen took a chunk from his "gamer" in practice Thursday.

Nilsson is expected to make a start with back-to-back games leading into the break.

The netminder devoted sections on his mask to "Hockey Fights Cancer," and also showed support for the LBGT community with a rainbow flag. Here's hoping he's got a similar design to unwrap over the holidays.
