Toronto Maple Leafs forward Sam Lafferty was fined $3,108.11 by the NHL Department of Player Safety on Sunday for cross-checking Ross Colton of the Tampa Bay Lightning.
The fine was the maximum allowed under the league's collective bargaining agreement.
Lafferty lowered the boom on Colton with 4:50 remaining in the second period of Toronto's 4-3 overtime victory on Saturday in Game 3 of their Eastern Conference first-round series. Lafferty was assessed a minor penalty for roughing.
The Maple Leafs hold a 2-1 lead in the best-of-seven series heading into Monday's Game 4 in Tampa.
Lafferty, 28, has one assist in three games during the playoffs. He totaled 27 points (12 goals, 15 assists) in 70 games split between the Chicago Blackhawks and Maple Leafs this season.
