Tyler's younger brother Ryan tweeted, "Please keep my family in your prayers tonight."

Hilinski, 21, appeared in 11 games for Washington State in two years. He threw for 1,176 yards and seven touchdowns with seven interceptions as a sophomore in 2017.

His first career start was the Cougars' 42-17 Holiday Bowl defeat to the Michigan State Spartans. He was 39-of-50 for 272 yards and two touchdowns with an interception.

Hilinski's best game was Washington State's 58-37 loss to the Arizona Wildcats in October. He had 509 yards through the air on 45-of-61 passing.

With Luke Falk graduating, Hilinski was among the early favorites to take over as the Cougars' starting quarterback in 2018.
