Elsewhere, Robby Fabbri of the St. Louis Blues, Luke Kunin of the Florida Panthers and Guillaume Brisebois of the Vancouver Canucks were also waived by their respective teams.

But it is Mangiapane that is the biggest eye-opener on the list.

The winger signed a two-year, $7.2 million deal with the Oilers on July 1 with the goal of providing offensive depth behind the likes of Connor McDavid and Leon Draisaitl.

It hasn’t worked out. Mangiapane has just seven goals and seven assists in 52 games on the season along with a career-worst plus/minus of -19 while enduring multiple healthy scratches. The Toronto native is in his ninth NHL season, with three prior 20-goal campaigns to his name.

The five-foot-10, 183-pound Mangiapane was a sixth-round draft pick (166th overall) of the Calgary Flames in the 2015 NHL draft. He has 257 career points (130 goals, 127 assists) across 550 games having also played for Calgary and Washington.

Regula, also in his first season with the Oilers, has struggled with three assists and a minus-16 across 29 games. He recently spent time in the AHL on a conditioning stint.

Fabbri, 30, has just one goal and three assists in 15 games with the Blues.

Kunin has appeared in 44 games with the Panthers, recording two goals and two assists.

Brisebois has not skated in a game with the Canucks this season.
