Simon Cvijanovic spent several hours Sunday night posting a series of tweets accusing his former football coach at the University of Illinois of pushing injured players to play hurt.

The former Fighting Illini offensive lineman first posted around 5 p.m. ET, saying he had to quit playing football due to "physical health." He then indicated Tim Beckman, Illinois' head football coach, ran him and other hurt players out on the field despite any injuries. His last post was shortly after 2:30 a.m.

According to ESPN, Cvijanovic hurt his shoulder and knee in 2013 and 2014, but it was psychological issues stemming from the injuries that forced him to stop playing football.

Cvijanovic said in one post he decided to go public with his claims because he was not invited to the Illini's senior banquet and later confronted Beckman with the matter. He cited honors such as starting four years, being named a team media rep at the Big Ten media days and earning two game MVP honors before alleging Beckman labeled him a "quitter."

In one tweet, Cvijanovic said the team had a head trainer named Toby Harkins who was not a licensed professional. Though Harkins was apparently fired, the alleged mistreatment of current and former players continued, Cvijanovic said.

As the Champaign Room noted, other Illini players responded to Cvijanovic series of tweets with some supporting his claims and others defending Beckman.

Cvijanovic also has a brother who is committed to Illinois for football. When someone asked why his family would allow their son to play for such a coach, Cvijanovic said he was under the impression Beckman would be losing his job.

Beckman responded to the allegations in a statement from the Illinois athletic department, but it is unclear if these allegations will lead to an investigation.

"Simon Cvijanovic was a valued member of the University of Illinois football team. He chose to leave the team during the 2014 regular season and withdrew from the university before the end of the semester," the coach said. "Upon his return for the spring semester, we have continued to support him with medical care an academic scholarship and academic advising. We cannot make any student accept our support. We wish him success in completing his degree, and we wish him the best of success in whatever he pursues after he graduates."
