Hossa spent the first seven years of his career with Senators before being traded to the Atlanta Thrashers for Dany Heatley before the 2005-06 season.
Hossa has the third most goals in Senators history with 188 and is sixth in points with 390. Against the Senators, Hossa has three goals and 18 points in just 12 games.
His former teammates understand playing against him -- and the Hawks -- will be a test.
"It's a big challenge. They're a great hockey team. We're looking forward to this game," said Senators forward Mike Fisher, who has been with the team since 1999. "We got to be really good tonight and try to shut Marian down."
The Senators have won three consecutive games, outscoring their opponents 11-3. They defeated Bruins 5-1 Monday afternoon in Boston.
The return of Daniel Alfredsson has been a spark for Ottawa, which is 16-8-3 on its home ice. The Senators captain has four goals in his last two games since coming back from a shoulder injury.
"If you look at their team, they've got some pretty offensive skills players that you got to be aware of when you're on the ice," Hawks winger Patrick Kane said. "It's one of those teams you don't see a lot, so you really don't know what to expect too much. I think for us we want to come out and push the pace right away and play at our pace, so we're not playing their type of game to start."
Slap shots: Defenseman Niklas Hjalmarsson didn't participate in the Hawks' morning skate, but coach Joel Quenneville said he should play tonight ... Defenseman Brent Sopel will also play. Sopel left Sunday's win at Detroit with an apparent arm injury, but did return.
