All-Star Weekend begins Saturday with the 2018 GEICO NHL All-Star Skills Competition (7 p.m. ET; NBCSN, CBC, SN, TVA Sports). The game at Amalie Arena is Sunday (3:30 p.m. ET; NBC, CBC, SN, TVA Sports).
Marchand was fined the maximum $10,000 on Jan. 26 last season, three days before playing in the 2017 All-Star Game, for a dangerous trip of Detroit Red Wings defenseman Niklas Kronwall.
Marchand's suspension will begin Thursday when the Bruins play at the Ottawa Senators. He can return Feb. 7 at the New York Rangers.
Marchand, who previously was suspended five times for a total of 14 games, is considered a repeat offender under the terms of the collective bargaining agreement.
He was suspended two games at the end of last season for spearing Tampa Bay Lightning defenseman Jake Dotchin, three games for clipping Ottawa Senators defenseman Mark Borowiecki in 2015-16, two games for slew-footing New York Rangers forward Derick Brassard in 2014-15, five games for clipping Vancouver Canucks defenseman Sami Salo in 2011-12, and two games for elbowing R.J. Umberger of the Columbus Blue Jackets in 2010-11.
