Andrighetto was hurt during the preseason in a game against the Dallas Stars on Sept. 26 at Pepsi Center. His first full-contact practice with the team on Wednesday.
He will replace rookie Sheldon Dries on a line with Vladislav Kamenev and Gabriel Bourque.
"I think he looks quick, he is in really good shape," Bednar said of Andrighetto following Wednesday's practice. "He has done a lot of hard work since he's been out. I'm excited to have a guy like him available again, adds some skill and some speed to our lineup."
The Zurich, Switzerland, native recorded 22 points (eight goals, 14 assists) and skated in a career-high 50 games last season despite missing 28 games with injury.
Having watched his club's first six outings of the campaign from afar, Andrighetto has liked what he has seen from the group.
"Early in the season right now obviously there is still some stuff that we have to clean up, but I have been really impressed," he said. "Especially with the speed that we have through all four lines. I mean the whole team, we are playing a really fast game, some teams have trouble keeping up with us, which is exactly how we want to play.
"Now looking back at the last two games, they are really tight. I mean we lost the last two but it was in overtime and a shootout, it can go either way. I have really liked so far what I have seen, and I am excited to be part of it and jump in there and help even more."
