A special board meeting took place Friday night but results of the vote were unavailable at press time.
Hubble has been at Guyer since 2005, where he was part of the staff when the school officially opened in 2005.
The 38-year-old Hubble, who is a Jacksboro native has been a part of a program that has gone 75-15 since 2005 with a combined 30 playoff games over the past six years, winning the last two state titles in 2012 and 2013 in Class 4A-Division I.
Despite being a part of the Guyer juggernaut, Hubble had stints at smaller schools, with stops at his hometown Jacksboro, Dublin and New Caney.
Hubble is the second Guyer assistant to get a head coaching job this week, joining longtime running backs coach/special teams coordinator Oschlor Flemming, who accepted an offer to become the head coach at Fort Bend Dulles.
Both will be first-time head coaches. Breckenridge will play in District 4-3A DI in the next two-year realignment.
In his letter of application, Hubbell said “Even though Breckenridge has a rich tradition of excellence, I believe I can re-establish Breckenridge as a championship program that is a state contender year-in and year out. I want to bring the combination of the program that Coach (John) Walsh and our staff have developed and my vision to Breckenridge.
