Blackhawks coach Joel Quenneville scratched Regin and opted instead to use defenseman Sheldon Brookbank as a forward against the Avalanche. Brookbank had zero shots, one five-minute penalty for fighting, a minus-one rating and played eight shifts for 4:33 of ice time in the 3-2 loss to the Avalanche.
Regin said he had a brief conversation with Quenneville about the scratch and believes the scratch had to do with roster numbers rather than his play.
"I don't read too much into it," Regin said after the team's morning skate on Friday. "We [have] more guys that have to play every game, so somebody's going to sit out. I'm trying not to read too much into it and focus on what I can do tonight.
"I've been around a couple years. It's something you learn to deal with. Focus on the next task. That's tonight. Now I have a chance to prove I want to be in the lineup."
Regin has played center in all five games for the Blackhawks since being acquired from the New York Islanders in February. Quenneville said he plans to play him at wing against the Nashville Predators on Friday. Regin played right wing alongside center Andrew Shaw and left wing Bryan Bickell during the morning skate.
"He's all right," Quenneville said of Regin's play. "We're going to put him on the wing tonight. I don't think we've seen him there yet. We're going to try him there and get [Shaw] back to the middle and see how that works."
Regin played wing and center for the Islanders, so he does have experience at various positions.
"It should be fine," Regin said. "Try to keep it simple and try to skate a lot on that wing and try to create something."
Regin has one goal and a zero rating with the Blackhawks. He has three goals, five assists and a minus-10 rating in 49 total games this season.
