"To be honest with you, I didn't think he would be himself until Christmas. We're right on pace for that," Boucher said. "He's getting better every game. I really like his last games. He's getting his mobility back. He's getting his stamina back. He's getting his timing back."
The Senators are 2-10-2 in their past 14 games but are coming off
a 3-2 win against the New York Rangers
at Canadian Tire Centre on Wednesday.
Karlsson said as the season progresses, talk about his injury recovery will die down.
"At the end of the day, as we get deeper into the season, it's not going to be an issue for me at all. I think the big thing is going to be for me to be able to work on it next summer and the offseason and get my strength back and everything," Karlsson, 27, said. "By then, we won't be able to talk about his anymore."
Boucher said it was understood the physical rehabilitation would take a certain amount of time. He's encouraged lately by Karlsson's attitude.
"Probably what's been the toughest for him has been mentally," Boucher said. "Knowing what he is, what he can do, but not being able to have that fraction of a second that makes him himself, it is frustrating," he said. "When you know you can help your team win, and you see your team wasn't winning, that's more frustrating.
"What I like is his mind now. There's been a few games now where he's been a lot calmer, accepts the process. It's been a lot better and it's going to keep on getting better. It's a normal process. He's probably going to do it faster than anybody I know in those type of circumstances, but it's taken the time it's taken. That's where we're going."
