June Jones, a longtime football coach who made an impact at the college level, died at the age of 73 on Thursday.

Jones was placed in hospice care two weeks ago, as he’s dealt with health issues earlier this year, per the Honolulu Star-Advertiser.

The University of Hawai’i, where Jones served as head coach from 1999-2007 after playing quarterback for the Rainbow Warriors, confirmed his death.

Timmy Chang, Hawai’i’s current head coach, became the NCAA’s all-time passing yards leader under the tutelage of Jones. He said "words can’t express the sorrow" he feels learning of his old coach’s passing.

"Coach Jones was a father figure, a mentor, and a visionary who revolutionized the game," Chang said in a statement, per ESPN. "He believed in a young kid from Hawai’i and gave me the opportunity of a lifetime to run his offense. And his impact didn’t stop when my playing days ended. He guided me every step of the way as I transitioned into coaching, always making time to share his wisdom and support me when I took over this program.

"He put Hawai'i football on the map and showed us all what was possible. We lost a true legend today, but I will spend the rest of my career trying to honor his legacy, his passion for this university and the Aloha he shared with everyone he touched. My deepest condolences go out to his 'ohana and all those who he impacted."

After playing college ball at Hawai’i, Portland State and Oregon, Jones signed as an undrafted free agent with the Atlanta Falcons, whom he spent four seasons with, backing up quarterback Steve Bartkowski. He started five games in his NFL career, winning just one.

Jones’ coaching career began right after his playing days were over. He eventually worked his way to become the Falcons’ head coach from 1994-96, and he would be named the interim head coach of the San Diego Chargers in 1998.

He had an opportunity to remain in place, but he decided to head back to Hawai’i to become its head coach. Jones led the Rainbow Warriors to conference titles in 1999 and 2007, the latter season being a historic one.

Hawai’i began the season 12-0 and made the school’s first-ever BCS bowl game (Sugar Bowl).

"The 2007 season and making the Sugar Bowl, that went over what anybody ever thought was possible," Honolulu Mayor Rick Blangiardi, a former Rainbow Warriors player and assistant coach, said in a statement. "I was on the field for the game [against] the University of Washington. We were down 21 points, not once but twice, and still came back to win against a very formidable opponent. That kind of coaching and who he was was very, very special. He leaves an incredible legacy here. June was very special, we will miss him, but his legacy will live on."

Jones’ career took him to SMU next, where he was head coach from 2008-14. He also coached in the USFL and CFL.
