Jackson sank four 3-pointers, made a total of six shots and his 16 points in the first half were only six points less than what all of Arkansas' players had combined.
But there wasn't much of a drop-off after Jackson sprained his ankle while going up for a shot less than three minutes into the second half.
With their leading scorer forced to take a seat down the stretch, Texas Tech's Charlie Burgess and Martin Zeno picked up the slack and carried the Red Raiders to a 71-56 win in front of a crowd of 13,283 in Alltel Arena.
"I think that was really important that they didn't really say, 'What are we going to do now (that Jackson is hurt)?" Texas Tech coach Bob Knight said.
Burgess scored 13 of his team-high 19 points in the second half, and Zeno added another 11 points to help Texas Tech maintain the double-digit lead it built in the first half when Jackson was practically unstoppable.
After a pair of free throws by Arkansas forward Charles Thomas cut the lead to 45-37 with 9:33 remaining, Zeno took over by hitting jumpers, getting to the free-throw line and giving his team a much-needed spark.
The 6-foot-5, 208-pound forward scored nine straight points for the Red Raiders to push their lead to 54-41 with 5:53 left, and Burgess added a layup 24 seconds later to keep the offense rolling without Jackson.
"I think they just have great heart. They didn't really worry about (my ankle)," Jackson said. "They just kept continuing to play the game and executing the game plan."
Jackson made 6 of 9 shots in the first half, including 4-for-5 from behind the 3-point arc despite being defended at times by Arkansas guards Gary Ervin, Patrick Beverley and Stefan Welsh.
But Jackson was unable to contribute much in the second half after he limped off the court with 17:22 remaining. He missed all three shots he attempted, scored his only point of the second half on a free throw and admitted afterward that he felt a step slower because of the sprained ankle.
"It's a little sour right now, but I'll be all right, though," Jackson said.
With the guard forced to sit for a roughly 10-minute stretch in the second half, Burgess and Zeno assumed much of the scoring for Texas Tech.
Burgess scored seven of the Red Raiders' final nine points over the final 3:02 to fend off any hope by the Razorbacks of sparking a rally.
Anytime Arkansas made a basket to cut into the lead, Burgess responded down the stretch with either a pair of free throws, a 3-pointer or a layup while streaking down the baseline.
"Once (Jackson) was out, everyone had to pick it up after that," Burgess said.
