NASHVILLE, Tenn. (AP) — The NHL has fined Nashville defenseman Shea Weber $2,500 for slamming Detroit forward Henrik Zetterberg’s head against the glass at the end of Game 1.

Weber was assessed a minor penalty for roughing, and the NHL announced the fine Thursday while the Predators were practicing. The league noted the fine was the maximum allowed under the Collective Bargaining Agreement.

WATCH: Shea Weber Slams Henrik Zetterberg’s Head Into The Glass

Brendan Shanahan, the NHL’s chief disciplinarian, says it was a reckless and reactionary play with Weber throwing a glancing punch before shoving Zetterberg’s head into the glass. Shanahan says league officials were told Zetterberg did not suffer an apparent injury and is expected to play Friday in Game 2.

The NHL notes the play will be a factor if Weber is involved in any further incidents in the postseason.
