Backup Chad Henne took over, but he couldn't turn around a contest that ultimately produced more questions than answers for Jacksonville's offense.
Gabbert's day was messy from the outset. His 7-of-19 outing for 53 yards and a touchdown marked his lowest yardage as a pro. Take away his 32-yard completion to Laurent Robinson, and Gabbert's five remaining connections averaged less than five yards a pop.
Jacksonville sputtered through five three-and-outs at one stage. The offensive line was overwhelmed by Houston's defense, leaving Gabbert to face a collapsing pocket all afternoon.
It read like a page ripped from last year's shaky narrative for the Jaguars. That's not a book anyone in Jacksonville was hoping to re-read in 2012.
