They had to wait until the Maple Leafs concluded their regular season against the Blue Jackets, but after Toronto blew a 2-0 lead and lost 3-2 in regulation on Sunday, the Bruins now know their first round opponent.

For the first time in franchise history, the Black and Gold will meet the Ottawa Senators in the Stanley Cup Playoffs. The first matchup between the two teams takes place on Wednesday night at the Canadian Tire Centre.

For the first time since their franchise’s inception in 1992, the Sens swept the Bruins in the season series. The Black and Gold only notched one point against their Atlantic Division rivals during the 2016-17 season. That came this past Thursday night at TD Garden during their 2-1 shootout loss against Craig Anderson and company.

Though they may have Brad Marchand back in the fold after his two-game suspension for spearing Jake Dotchin, the Bruins may be without two of their top-four defensemen in Brandon Carlo and Torey Krug. Both left the last two games of the season due to respective upper-body and lower-body injuries. Depending on Carlo and Krug’s injury severity, the three days off between Games 1 and 2 could prove to be beneficial to the blue-liners.

After Saturday afternoon, the series transitions to Boston for Games 3 and 4 next Monday and Wednesday. If necessary, Game 5 will be played in Ottawa a week from Friday; Game 6 in Boston on Sunday, April 23; and Game 7 will be back in the Canadian Capital on Wednesday, April 26.
