In the 2023-24 NHL season, MacKenzie Weegar and Rasmus Andersson played more ice time together than any other two members of the Calgary Flames: 947 minutes and 15 seconds, to be exact, and they were still teammates as recently as this season.
On Friday, they repeatedly punched each other in the face.
No matter how many dinner outings and golf rounds the pair shared over their three and a half seasons as teammates, the Stanley Cup Playoffs arenât the time to exchange pleasantries.
âJust two competitors competing against each other,â Weegar said of the tussle. âObviously, in a playoff series like this, thereâs no friends out there. Itâs not personal.â
Mikhail Sergachev and MacKenzie Weegar engaged in a physical fight, repeatedly punching each other during a playoff game.
They played together for three and a half seasons, with significant ice time during the 2023-24 NHL season.
The fight occurred during a playoff game between the Utah Mammoth and the Vegas Golden Knights.
Fighting is common in the Stanley Cup Playoffs due to the heightened emotions and intensity of the competition.

Andersson is responsible for the cut and swollen left eyebrow Weegar sported after the game.
âHe got me good, but thatâs alright â I like it. I like a little blood."
The two began this season as teammates with the Flames. They were in the visiting locker room for the Utah Mammothâs home opener, and Andersson even scored the first goal of the season at the Delta Center.
After missing the playoffs on a mere tiebreaker last year, the Flames had high hopes for this season. But when it was clear that they wouldnât achieve much and that Andersson, one of their biggest stars, was unlikely to re-sign, they went full rebuild mode.
It began with Anderssonâs trade to the Vegas Golden Knights in January. Weegar went next with a trade to the Mammoth a few days before the trade deadline, after which Nazem Kadri returned to the Colorado Avalanche in a deal that wasnât announced until more than an hour after the deadline had passed.
Itâs entirely possible that the winner of the ongoing playoff series between the Mammoth and Golden Knights could end up facing Kadri, one of the leagueâs most notorious pests, in the Western Conference Finals.
If it gets to that point, fans can expect at least the same level of competitiveness between the former teammates.
Weegar scored four goals in his 79 regular-season games this year. Through just three playoff games, heâs already halfway to that total with a pair of goals.
He has Andersson to thank for the first one, as it almost looked like Andersson kicked Weegarâs shot from the point in Game 2 into the net.
In Game 3, Weegar scored the first-ever playoff goal at the Delta Center on another point shot.
âI saw one fan when I banged on the glass,â Weegar said of the experience. âWe had a special moment. Iâm not sure who that was, but Iâm sure heâll remember it, along with myself.â
Weegar added an assist in the second period for three total points in the series. Heâs now tied with seven others as the series leaders in the points column.
The veteran defenseman still has some adjusting to do on the defensive side of the puck, but he looks more and more comfortable with each passing game.
Heâs beginning to show why the Mammoth valued him so highly when they acquired him.
