The 24-year-old said he sustained the injury while throwing a "wild punch that didn't connect" during a fight with Calgary's Mathew Tkachuk on Dec. 15. Sitting in the penalty box afterward, Dumba originally thought a brace and some Tylenol would be all he'd need to return to action.
But when team staff took a closer look, "it was basically a no go," Dumba said.
Tkachuk dropped the mitts with Dumba 40 seconds in in retaliation for a hit Dumba delivered Dec. 6 at Calgary, injuring forward Mikael Backlund. Dumba didn't receive a penalty or any discipline from the NHL.
"I'd expected it," Dumba said. "I can't hold any hard feelings for it. I knew I was going to fight that night; it's nothing I've ever shied away from before. I have a number of fights from throughout my NHL career, so it's not like it's anything out of the norm. I guess when I sit back and look at it, you can kind of scratch your head and wonder. I think I paid. It wasn't really warranted. It was a clean hit, nothing from the NHL, no penalty on the play."
Perhaps most disappointing was the season Dumba was having before the injury. Taking and connecting on more shots, he led NHL defensemen with 12 goals. His 22 points and 23:23 average ice time in 32 games were second among Wild defenseman to Ryan Suter.
"No one stole this from me," said, Dumba, who signed a five-year, $30 million contract during the offseason. "It's just what happened. You have to deal with it and live with it. If you get caught up in what could've been, it leads to just you being sad and depressed during this whole thing. I'm not about to do that. I'll be back eventually, whether it's this year or next. I'll do the same thing. I'm not worried."
In the meantime, Dumba has been at the rink daily to rehab and see his teammates at morning skates and practices. He's taken to tweeting support for his comrades while watching games and wishing he could help Minnesota put together a coveted win streak.
He also watched friend and former roommate Nino Niederreiter get traded to Carolina Thursday in exchange for Victor Rask.
