Strong says Heard will be evaluated during the week and could play if cleared by team doctors.
Swoopes, a junior, started most of 2014 and the first game of this season, but was replaced by Heard after a blowout loss at Notre Dame in the season opener. Heard was knocked of the game in the first half of last week's loss against Texas Tech.
The loss dropped Texas to 4-7 and guaranteed a second consecutive losing season in Strong's second year.
Swoopes has passed for 386 yards and three touchdowns. He also has 11 rushing touchdowns.
