The long-awaited Radko Gudas grudge match has been thrown into doubt.

Gudas didn’t suit up for his Anaheim Ducks against the Edmonton Oilers on Saturday due to an injury sustained Thursday against the Calgary Flames.

According to Ducks head coach Joel Quenneville, Gudas is day-to-day, and the team expects to know more on Sunday.

The absence of the Ducks’ captain puts into question whether he will play Monday against the Toronto Maple Leafs, when the two teams meet for the first time since Gudas ended Auston Matthews’ season early.

He was suspended for five games for the play, a ruling that raised eyebrows across the league.

Gudas, who also injured Canada captain Sidney Crosby at the Olympics, was seen in a walking boot earlier Saturday, per Sportsnet’s Elliotte Friedman.

In 54 games this season, the Czech has two goals, 11 assists and 45 penalty minutes.
