Former Mississippi State defensive lineman Jeffery Simmons, a projected first-round pick in the NFL Draft, has suffered a devastating injury.

According to ESPN, Simmons suffered a knee injury during training that is thought to be a torn ACL, league sources tell ESPN's Adam Schefter and Chris Mortensen.

An official statement that goes into detail about the injury will soon be released, according to the outlet.

“Simmons was rated as the No. 12 overall draft prospect in the latest big board from ESPN's Mel Kiper, and he was projected to be the No. 7 overall pick by the Jaguars in ESPN draft expert Todd McShay's latest mock draft. A top prospect coming out of high school, Simmons was captured on video hitting a woman; the incident took place before Simmons arrived at Mississippi State. He later pleaded no contest to simple assault.”

This means that Jeffery Simmons, whether knowingly or not, “shook up” the first round of the NFL draft. According to CBS, if it turns out that the injury is a torn ACL, he'll be sitting out most — if not all — of his rookie season to rehabilitate, which isn't a good sign of things to come. And it's only been made worse by his existing issues.

“Simmons, who had 30 tackles for loss and seven sacks during the past two seasons as Mississippi State and is considered one of the top available defensive linemen in the draft, was already facing questions regarding off-the-field issues. He had previously been informed that he would not receive an invitation to the NFL Combine due to the league's rule regarding issues of violence. “
