Brendan Shanahan was busy Thursday in his first season as the NHL's dean of discipline. He also banned Calgary forward Pierre-Luc Letourneau-Leblond for the rest of the preseason and the Flames' first game of the regular season.
Shelley received a five-minute boarding penalty for hitting Boyce when Boyce was facing the end boards. Immediately after the hit, Toronto's Jay Rosehill and Shelley engaged in a lengthy fight. Shelley left the ice with the right side of his face bloodied. Both players received fighting majors, and Shelley was also given a game misconduct.
Shelley can return Oct. 20 vs. Washington. He was suspended twice last season.
