David Desharnais’s stint in the press box was short-lived.

After scratching the struggling forward from the lineup for Tuesday’s shootout loss to the St. Louis Blues, coach Michel Therrien confirmed Desharnais will be back in the lineup Thursday when the Canadiens play the Ottawa Senators in Kanata, Ont. (7 p.m., CBC, RDS, TSN Radio 690).

“We wanted him to take a step back and we didn’t want to wait too long to bring him back in the lineup,” Therrien said after practice Wednesday in Brossard.

“That was our goal. I believe when a player is facing a situation like he’s facing right now, you don’t want to start to think in the stands too long. We want to give him a chance. We want to show him support,” added Therrien, calling Desharnais an important player for the team.

The coach expects more from him “and I expect more from myself,” said Desharnais, who only has one point this season.

“And I know that. So just got to bring it next game.”

There was a bit of line juggling at practice, and when it ended Desharnais centred a line with Rene Bourque and rookie Michaël Bournival, who has been playing alongside Tomas Plekanec and Brian Gionta. Max Pacioretty shifted over to Plekanec’s line.

“A guy like Bournival brings a lot of energy to a line by his work ethic, by his pursuit of the puck-carrier (he’s) quick on loose pucks,” Therrien said.

Bringing new energy sometimes to some players can be very positive, the coach explained.

Lars Eller was back on the Kid Line with Alex Galchenyuk and Brendan Gallagher. Therrien had switched Galchenyuk to centre during the third period last Saturday against the Colorado Avalanche and again on Tuesday against the Blues when Desharnais was a healthy scratch.

They took the opportunity to see where he’s at as a centreman, Therrien said.

“It’s a process,” the coach added. “It’s like yes, we want things to happen really quick at times. But the reality — it’s step by step. You learn how to walk before running. And this is what we’re doing with Alex and he’s doing really good with that.”

Therrien said he thought Galchenyuk was thinking a bit too much against the Blues and was a little less effective in the faceoff circle. But there will be other occasions this season where they’ll put him at centre again, the coach said.

Galchenyuk didn’t seem fazed by the brief nature of the experiment and switching back to the wing.

“Honestly, I don’t care,” the 19-year-old said. “I want to help the team win. And wherever the coaches think I’m better positioned — whether it’s wing or centre — it’s fine with me.”

Galchenyuk went 1-6 in the faceoff circle against the Blues, although he couldn’t recall winning a single draw.

“I didn’t expect it to be that tough,” he said. “It was a tough day for me in the circle, for sure.”
