NASHVILLE, Tenn. -- Maurice Jones-Drew and the Jacksonville Jaguars are having fun trying to run their way to an AFC South title.

Jones-Drew turned in the NFL's second-best rushing effort of the season with 186 yards on 31 carries, and Rashad Jennings and quarterback David Garrard each ran for a touchdown in the Jaguars' 17-6 victory over the Tennessee Titans on Sunday.

Houston's Arian Foster has the top rushing game this season with 231 yards against Indianapolis on Sept. 12.

"Obviously, Maurice Jones-Drew was special today, and we rode Maurice hard today," Jacksonville coach Jack Del Rio said. "He had a superb game."

With their fourth win in five games, the Jaguars (7-5) took over first-place in the AFC South, a game ahead of the Colts (6-6), who lost to Dallas 38-35 in overtime.

Jones-Drew has run for at least 100 yards now in five straight games, but his latest may have been his easiest.

"I only had to make one guy miss most of the time, and the guys were doing a great job of keeping guys off me," Jones-Drew said. "That performance was a total team effort."

The Jaguars got a bit of revenge for a 30-3 loss to Tennessee on Oct. 18 by taking control on the ground from the start on a cold, windy day. They scored on their opening drive by running through and over the Titans to split the season series. Jennings scored on an 11-yard run to cap the 12-play, 77-yard drive.

"They are a physical team, and we had to be physical today," Jaguars center Brad Meester said. "We were able to run the ball and keep pounding it, and that was key for us."

Tennessee (5-7) started veteran Kerry Collins at quarterback with offensive coordinator Mike Heimerdinger in the press box calling plays days after starting chemotherapy for cancer but unable to avoid a fifth straight loss. The Titans have now gone 13 quarters without an offensive touchdown.
