Jags rookie QB Gabbert injured, returns
Gabbert bruised his ribs on an 11-yard run on Jacksonville's first series. He slid at the end of the run and Houston's Brian Cushing fell on top of him.
He remained on the grass for a couple of minutes and was looked at by trainers before being helped off the field.
He returned for the next series in the first quarter.
Gabbert, the 10th overall pick in this year's draft, was replaced by Luke McCown before returning.
Houston linebacker Darryl Sharpton suffered an apparent right leg injury in the second quarter on a run by Maurice Jones-Drew. Trainers placed a brace on his leg and he was carted off the field.
