Olli Maatta returned to the Blackhawks lineup after missing four games with flu-like symptoms.
The defenseman said what he thought was a simple cold that wouldn't keep him off the ice long developed into something more and sapped him of his energy.
"When I got it I thought I could play the next game right away," Maatta said. "It kept getting worse and worse and finally after a couple of days of practice I … feel like I'm back in game shape."
Maatta had been skating but wasn't ready to draw back into the lineup until Thursday.
"When you're down for five days it's more just get back in shape," said Maatta, who was paired with Connor Murphy against the Coyotes. "It's both legs and lungs and it just feels like you get gassed a little more easily. I finally feel pretty good."
The timing for Maatta's return couldn't be better for a Blackhawks team still reeling from the loss of blue liner Calvin de Haan to a right shoulder injury suffered against the Golden Knights on Tuesday night in Las Vegas. With Duncan Keith still sidelined with a groin injury, de Haan was logging heavy minutes but is back in Chicago undergoing further evaluation on his shoulder.
"It's tough to see 'Cal' go down," Maatta said. "We've been without Duncan for a little bit but the other guys have to step up. It's not a one-man job, everybody has to play those minutes."
Colliton said that Maatta and de Haan "kind of have a similar profile, defensive, puck moving, try to kill penalties for us and play a simple game. Hopefully, (Maatta) can bring that for us."
As far as de Haan's status, Colliton said he didn't yet have a final evaluation of the injury but it's "likely" to be a long-term issue.
