Nebraska’s Senior Day battle against Wisconsin is not off to a hot start.

Marques Buford Jr, a key safety for the Huskers, appeared to injure his knee after jumping over a few Wisconsin defenders. He was carted off, firing up his teammates as he went.

Here’s a warning for those who do not like to see bad injuries.

Robert Griffin III saw the injury and knew immediately it did not look good. He shared his thoughts on Twitter following the play.

His status has not been officially updated as of early Saturday afternoon.
