LAS VEGAS (WPVI) -- UNLV football player Ryan Keeler died Monday in Las Vegas, the school announced.

Keeler, a 20-year-old defensive lineman from Chicago, spent last season with UNLV after starting his college career at Rutgers. UNLV did not provide a cause of death.

Rutgers head coach Greg Schiano said in a statement, "We are devastated to hear of Ryan's passing. From getting to know him as a recruit, to actually getting to coach him, what stood out most was his passion. His passion for his teammates and his passion for the game of football. We send our love and prayers to Ryan's family and friends during this difficult time."

"While I had the honor of knowing Ryan for only a couple of months, he already stood out to our coaching staff as an incredible person, student and teammate," Rebels coach Barry Odom said in a statement. "Our condolences and prayers go out to Ryan's family as we grieve along with them over this tremendous loss."

Keeler appeared in seven games for UNLV last season, recording eight tackles and a sack. He earned academic All-Mountain West honors with a 3.8 GPA.
