The future of professional lacrosse in Rochester is uncertain.

The future of professional lacrosse in Rochester is uncertain after the owner of the Knighthawks announced he is leaving to start an expansion team in Halifax, Nova Scotia.

In a letter Thursday to fans, Knighthawks owner Curt Styres says he will leave the the team after the 2018-19 season.

According to the National Lacrosse League, Styres will bring many of the players on the current Knighthawks roster to the new Halifax franchise.

Styres has owned the Rochester team since 2008 and helped lead them to three championship titles.

Could Pegula Sports take over ownership of the Knighthawks?

At 1 p.m. Thursday, Terry and Kim Pegula will make an announcement alongside the National Lacrosse League at the Blue Cross Arena in Rochester where the Knighthawks play.

Back in July, the Pegulas reached an interim deal with the city to operate the downtown venue and Rochester Amerks.

Pegula Sports is the management company of the Buffalo Bills and the Sabres. They also manage the National Lacrosse League's Buffalo Bandits.
