Seton-LaSalle had goals of repeating as WPIAL and PIAA champions this season.
After falling just short of reaching the first goal, the Rebels will try to attain the second.
Seton-LaSalle, the No. 1 seed, was upset by rival Bishop Canevin, 56-47, in the WPIAL Class AA championship Saturday at Palumbo Center.
The Rebels, who were two-time defending champions, had defeated Bishop Canevin twice during the regular season.
Seton-LaSalle will open up PIAA tournament play Friday with a first round game against Kane at North Allegheny.
“[The players are] upset because they’re used to winning the WPIAL and the state,” Seton-LaSalle John Ashaolu said. “So they’re upset, but they know that we’re probably going to play [Bishop Canevin] again and they know our big goal is to be state champs. We still have that in mind.”
