HOUSTON(AP) -- Maurice Jones-Drew carried the Jacksonville Jaguars
to their first victory and trounced all over the good feelings
the Houston Texans had after their big win last week.

Jones-Drew had his first 100-yard game of the season and scored
three touchdowns to lead the Jaguars over the mistake-prone
Texans, 31-24 on Sunday.

Jones-Drew scored the go-ahead touchdown on an 8-yard run early
in the fourth quarter and finished with 119 yards rushing.

"Each play we got better," Jones-Drew said. "Each time we got to
the sideline we got better. We just kept believing in each other
and that was the best thing about it ... they jumped out on us
real quick. We just kept fighting back, fighting back. No one
blinked."

Jacksonville became the third straight team to run over
Houston's NFL-worst run defense. The Texans allowed 190 yards to
the Jets, 240 to the Titans and 184 on Sunday.

"A loss is devastating regardless (but) especially so after what
we did last week," Houston's Mario Williams said, referring to a
34-31 road win over the Tennessee Titans.

Houston (1-2) had several chances to tie the game. The last came
when Chris Brown's goal line fumble was recovered by the Jaguars
(1-2) in the end zone. The Texans challenged but Jacksonville
kept the ball.

"When you let down all your teammates, you can't put it into
words," a distraught Brown said.

The Texans had a touchdown nullified two plays earlier when
Kevin Walter was called for offensive pass interference.

The Jaguars were driving with a seven-point lead and 4 1/2
minutes left when Houston's Dunta Robinson forced a fumble by
Mike Sims-Walker. Zac Diles recovered and the play was
challenged, but the ruling on the field stood and the Texans got
the ball.

The Jaguars forced Houston into a three and out after Clint
Ingram tripped Matt Schaub for the sack with about six minutes
left in the fourth quarter. Ingram jumped around after the hit
while the normally stoic Jack Del Rio broke into a huge smile.

Houston had a first down at the 17 but had to settle for a field
goal that tied it at 24 in the third after Schaub's run on third
down came up one yard short.

Jacksonville took the first drive of the second half 83 yards,
capped by a 1-yard touchdown run by Jones-Drew to regain the
lead, 24-21.

Del Rio was impressed with his team's halftime adjustments.

"They had kind of gone into the end of the first half there and
taken some momentum," he said. "Our team responded well, getting
the ball coming out of the half, going down and getting a score
there and letting them know that we were here, on a mission and
that we had the resolve to be in a dogfight and win this thing."

Schaub threw for 300 yards in the game and had three touchdowns
in the first half, but couldn't get anything going after
halftime.

He found Owen Daniels on an 2-yard reception for his third
touchdown pass to put Houston ahead 21-17 at halftime.

Houston kept that drive going with an 11-yard end around by
Walter on fourth-and-1 from inside the 20.

A week after Chris Johnson blew by Houston's defense for three
touchdowns of more than 50 yards, Jones-Drew scored his first
touchdown on a 61-yard run. The score put Jacksonville ahead
17-14 in the second quarter.

"We're giving up some big, big plays and struggling to stop
somebody," Houston coach Gary Kubiak said.

Walter put Houston on top 14-10 with a 9-yard touchdown catch in
the second quarter. It was his first action of the season after
sitting out the first two games with a hamstring injury.

Houston's Jacoby Jones scored for the second straight week on an
18-yard pass from Schaub that put the Texans up 7-3 in the first
quarter. Jones lost his shoe on the catch before bounding over
to his mother's front row seat behind the end zone for a hug.

Houston rookie Brian Cushing tipped one pass and broke up
another, but a late hit penalty late in the third quarter helped
propel the drive that put the Jaguars up 31-24.

Ernest Wilford looked to have scored on a 15-yard touchdown
reception early in the second quarter. Kubiak challenged the
call and after review, officials ruled that Wilford stepped out
of bounds at the 2-yard line.

Jacksonville didn't take long to put that score back on the
board when David Garrard ran in for the touchdown on the next
play to make it 10-7. Garrard finished 214 yards passing.

An interception by Rashean Mathis on Houston's first drive led
to a 52-yard field goal by Josh Scobee in the first quarter.

NOTES: Jacksonville SS Sean Considine suffered a groin injury,
but Del Rio wasn't sure of the extent of the injury after the
game. ... Houston WR Andre Johnson finished with 86 yards
receiving.
