Seabrook missed games in Los Angeles and Phoenix after the hit, which cost Wisniewski an eight-game suspension.
"He has skated three times now ... and he's looked fine," Hawks coach Joel Quenneville said Monday. "He seems ready to go."
The Hawks host the Phoenix Coyotes, who have a nine-game win streak, on Tuesday.
"I want to play," Seabrook said. "It's going to be up to the coaching staff and the trainers.
"I got better gradually, rode the bike, had some headaches and wanted to skate and get out there and started feeling better. I started feeling less pressure in the head."
But Seabrook hasn't been able to shake the disappointment of being injured by a friend. Wisniewski is a former Blackhawk who invited Seabrook to his wedding. Seabrook said Friday he's not sure if he's going to attend.
"Any time something like that happens, i think it's tough to handle, regardless," Seabrook said. "But coming from a friend, coming from a guy I know pretty good, it's got to be one of the most difficult things to get over."
