Jones, who elected to come back for his senior season instead of heading to the NFL as a first round draft pick, is returning off a junior season that featured him throwing for nearly 4,500 yards and 29 touchdowns to 15 interceptions.
He has netted 12,379 yards and 93 touchdowns so far in his career and looks to expand upon that.
Habern is back and healthy as a senior after missing five games in the middle of the 2011 season with a broken wrist and undergoing offseason back surgery.
This will be his third straight season as the starting center.
Hurst, a leader in what figures to be a renewed defense under new defensive coordinator Mike Stoops, led the team in 2011 with 11 pass breakups.
He also finished with 55 tackles, including four for loss, two fumble recoveries, a forced fumble and a 55-yard interception return.
The three and Stoops will convene at Big 12 Media Days when they take place July 23 and 24 at the Westin Galleria.
