Record-setting former University of Hawaii quarterback Colt Brennan has died at age 37 after being discovered unconscious at an in-patient rehabilitation facility in California, his family has confirmed.
Brennan was pronounced dead at Hoag Hospital in Newport, California on Monday. He had been in his fifth month of rehab when he was recently found unresponsive, his father Terry told the Honolulu Star Advertiser.
An exact cause of death has not been revealed, nor have any specifics about Brennan's battle with addiction.
'He was doing so well, the spark was back in his eyes, and he was healthy and doing great, and it happened,' said Terry Brennan, adding that he was surrounded by family when he passed.
'He went peacefully,' Terry continued. 'He listened to Bob Marley. His sisters had a lei around him when he was unconscious. They had the music of Bob Marley playing near his ear.'

After a brief stint with the NFL's Washington Redskins in 2008 and 2009, Brennan had struggled in recent years following the traumatic brain injury he suffered in a 2010 auto wreck.
He continued playing professional football, both in the Canadian and Arena leagues, but was later arrest several times for offenses ranging from driving under the influence to trespassing to filing a false police report.
As his father told the Star Advertiser, Colt's life had been turning around in rehab.
'He had been doing really [well],' Terry Brennan added. 'These guys were no-nonsense guys. It just got away from him. I don't know how else to explain it. Maybe one day I'll be able to explain it better.'
Brennan became a late-night football sensation with the unheralded Rainbow Warriors beginning in 2005, rewriting the NCAA record book when most college fans were asleep back on the continent.
Eventually, as he set new marks for touchdown passes in a career (131) and a single season (58 in 2006), fans began staying up late to catch some of Brennan's highlights against Western Athletic Conference competition.
'Colt Brennan's 2006 season was one of the most fun to watch in recent college football memory: 5,549 passing yards and 58 TD in 14 games,' ESPN's Field Yates wrote on Twitter. 'Those late Saturday night Hawaii games were must see. RIP and condolences to his family.'
In 2007, Brennan led Hawaii to a perfect 12-0 regular season before losing to fourth-ranked Georgia in the Sugar Bowl. The Rainbow Warriors finished the season ranked 19th in the country.
Brennan wasn't highly recruited after backing up future Heisman winner Matt Leinart at Mater Dei High School in Southern California.
Later, he was dismissed at the University of Colorado after allegedly trespassing into a female student's dorm room, exposing himself and fondling her, according to multiple reports. However, Brennan denied those charges and a guilty verdict for unlawful sexual contact was later vacated due to lack of evidence.
After being kicked off the Colorado football team, Brennan then enrolled at the University of Hawaii, where he instantly became a star, completing over 70 percent of his passes over three seasons as team's starting quarterback.
He finished sixth in the 2006 Heisman voting and third the following season, losing out to Florida's Tim Tebow.
Brennan's brief NFL career did lead to other opportunities, by which point he had already suffered the head injury that later ended his playing days.
He played for both the Hartford Colonials of the United Football League in 2011 and Saskatchewan in the CFL the following season before his head injury was determined to be too serious for him to continue on with his career.
Ultimately, Brennan's football career came to an end with the Arena League's Los Angeles Kiss in 2014 when neurological tests revealed the extent of his head injury.
'They did some tests, and there were major concerns about me playing football,' Brennan told the Star Advertiser in 2014. 'I was medically not cleared to play.'
