“Today was 100% my fault,” Blinn head coach Michael McBride said. “I didn’t set the lads up correctly, and I take full responsibility for the loss.”
Jacksonville scored in the 32nd and 57th minutes and out-shot the Bucs 16-9.
Blinn sophomore goalkeeper Kevin Pena made six saves in goal.
The Buccaneers resume their season with a region clash against No. 8 Tyler at 4 p.m. on Saturday, Sept. 17, in Tyler, Texas.
Blinn has competed in intercollegiate athletics since 1903 and captured 42 NJCAA national championships since 1987.
