"We went into a tough environment today," said SIUE Head Coach Jeremy Spates.
It was the first of two weekend matches against Big Ten opponents. SIUE next travels to Wisconsin, which previously came to the Cougar Classic earlier this season.
SIUE, 2-12, gave up bonus points to Northwestern, which used Senior Day to improve to 5-10 overall.
"Kevin and Sergio wrestled well, but I think we could have been much better as a team," said Spates.
Gschwendtner picked up a bonus point for the Cougars at 174 pounds, dispatching Northwestern's Braxton Cody 16-5. Villalobos followed up with a 4-2 decision over Brendan Devine at 184 pounds.
