The undrafted rookie will play alongside center Mika Zibanejad and right wing Jakob Silfverberg on Ottawa's second line. Conacher had nine goals and 15 assists in 35 games with the Tampa Bay Lightning this season before being traded to the Senators on Wednesday for goaltender Ben Bishop.
"I think we have a lot of speed on our line. Those two guys that I'm playing with are guys that are very confident with the puck and they're very patient," Conacher said. "They know how to make plays and, like I said, they're fast too, so they'll take pucks to the net pretty quick. So you've got to be ready for that."
Conacher grew up in Toronto and played at Canisius College in Buffalo, so he's expecting a big turnout of fans and family for the game.
"We certainly feel that motivation isn't going to be a concern for him. It might be over the top if it's going to be anything," Senators coach Paul MacLean said.
