Saad, who’s versatile enough to play either wing on any line, left Chicago’s 4-1 victory against the Detroit Red Wings on Sunday night at United Center with 7:39 remaining in the second period.
He didn’t return, and Blackhawks coach Joel Quenneville said he will be re-assessed Monday.
“He seemed all right here [after the game]," Quenneville said. "I don't think it's too serious, but we'll have a better idea [Monday]."
Saad, who has 19 goals and 25 assists in 68 games, didn’t have a point in 6:21 of ice time (11 shifts) Sunday.
