There's been many Dallas Cowboys players and coaches shaken over the death of linebacker Jerry Brown, but former teammates of his from his college days with the Illinois Fighting Illini are just as shocked by the series of events. Brown was killed in a car accident and his teammate, Josh Brent, was the driver.

Brent was driving while under the influence and has been charged with intoxication manslaughter. Some of their teammates from Illinois took to Twitter to express their sadness. Jeff Allen, who now plays with the Kansas City Chiefs, expressed his shock.

I'm still in shock. I don't want to believe it R.I.P Jerry Brown

Following that, Whitney Mercilus had a pair of Tweets in which he gave his condolences. Mercilus called them both great people and said "despite what people think," which probably means that many have lashed out at either Brent or both for the fact that drinking was involved in the accident.

R.I.P to the big homie Jerry Brown sad that he's gone before his time. 🙏

Current Illinois coach Tim Beckman took to Twitter to express his condolences as well, though he didn't coach either guy as he's in his first year.

Sad news for the Illini #Family today. Jerry Brown, former Illini and current NFL player has passed away. Keep him in your prayers.
