Gionta played in Montreal's 4-1 road victory against the Edmonton Oilers on Thursday night. He rejoined the team Tuesday after attending to a family emergency and played in a 3-2 loss to the Calgary Flames on Wednesday.
"We don't know when he's going to come back," Canadiens coach Michel Therrien said after practice at Rogers Arena on Friday. "He's an important part of our team. He's a good leader, but right now I don't know when he's going to come back."
Therrien confirmed that no callups will be made prior to the game Saturday and Ryan White will be back in the lineup after sitting out against the Oilers.
I definitely think going back down helped me, I had a lot of confidence down there, I played a lot of minutes and I think that helped me a lot. With the 37 games up here, that gave me experience as well. I know what it takes to play in the NHL and now it's time for me to show that I'm capable of being a full-time NHL player.
