The Maryland men’s lacrosse team’s matchup with Navy on Saturday has been postponed due to an outbreak of the Norovirus among the Midshipmen, both schools announced Friday.

The Terps claimed a 14-9 win in Annapolis last season, courtesy of hat-trick performances from attackmen Jared Bernhardt and Logan Wisnauskas, plus a five-piece from attackman Louis Dubick. With neither side having a free weekend until the end of the season, the game will likely be rescheduled in the midweek — if at all — as was the case when their matchup was last postponed in 2016.

The rivalry is particularly significant for Tillman, who spent 12 seasons as an assistant coach for the Midshipmen. Since being named head coach of Maryland, Tillman has gone 9-0 against his former employers, winning each game by three goals or more.

In a release, Maryland said the decision was made out of an “abundance of caution and for the sake of public health.” Single-game tickets will also be refunded.

Tillman’s squad now turns its sights to Notre Dame on Feb. 29, hoping to avenge its shock defeat to Villanova on Tuesday. The Midshipmen travel to Bethlehem, Pennsylvania, to take on Lehigh on the same day.
