Fleischmann took pregame line rushes with center Rickard Rakell and right wing Jiri Sekac but started the game with center Ryan Kesler and right wing Jakob Silfverberg. Right wing Emerson Etem was scratched.
Anaheim coach Bruce Boudreau left open the possibility of using one of his spare forwards after the Ducks and Blackhawks played their second multi-overtime game of the series in Game 4, a 5-4 Chicago win. Fleischmann has played in 33 Stanley Cup Playoff games.
"What he brings is experience," Boudreau said Monday. "He’s been through these wars; he’s played in these games. He’s had success in these games. I think earlier on in the playoffs he was very, very good against Winnipeg [in the first round]. So he could bring an option if we choose to go that route."
Fleischmann had not played since Game 5 of the second round against the Calgary Flames on May 10. He was initially used to fill in at center in Games 3 and 4 of the first round. He has one assist in four playoff games.
The best-of-7 series is tied 2-2. Game 6 is Thursday (8 p.m. ET; NBCSN, CBC, TVA Sports).
Chicago did not make any lineup changes.
