Scott Frost made the difficult announcement that electric running back Tre Bryant was retiring from the game of football. One of the most explosive backs in the Nebraska backfield last fall had serious knee pain and had decided to end his career.

After the statement from Frost, Bryant took to Twitter to make a public statement of his own, explaining his decision and thanking Nebraska fans for the continued support.

Bryant titled his statement “Time waits for no man.”

“Football is a physically demanding game as I would come to learn later in my career,” Bryant wrote. “Three knee surgeries later, I began to notice the passion I had for the game was being replaced with frustration…My body couldn’t keep up with the college grind and I had to learn to accept that. I am forever grateful for my journey as a football player.”

Below is his full statement.

Bryant played in just two games for the Huskers last fall, but tallied 299 yards and two touchdowns. The running back then suffered a season-ending injury, forcing him to miss the final 10 games of the year.

He was expected to be a dynamic piece of the Nebraska rushing attack again in 2018.

In two seasons in Lincoln, Bryant accounted for 471 yards and three touchdowns on the ground. He also tallied eight receptions for 56 yards and a score.
