FORT WORTH, Texas -- On a day TCU struggled on offense, its defense saved the day and its winning streak.
Lonta Hobbs ran for 124 yards and TCU stopped Tulane at the Horned Frogs 15 with 1:26 left to preserve a 17-10 victory Saturday.
TCU has won eight in a row, its longest streak since it won 12 straight in 1999-2000. The Frogs hold a half-game advantage over Southern Mississippi for the conference lead.
TCU didn't score an offensive touchdown for the first time this season but got help from a defense that set a school record by holding the Green Wave to minus-53 rushing yards, thanks in part to nine sacks.
Tulane had a four-game win streak snapped and totaled 115 yards of offense. Tulane scored 173 points over its previous four games.
"I challenged our defense at the beginning of the week to put another notch in their belt," TCU coach Gary Patterson said. "The big thing is we had a great pass offense and we were able to do some things up front to disrupt their offense."
ECU 54, HOUSTON 48 (3OT): The visiting Pirates fell behind by 17 in the third quarter before rallying.

Houston's Joffrey Reynolds rushed for a school-record 300 yards and four touchdowns, including a 25-yard run in the second overtime that forced a third.
East Carolina tied it at 34 with 2:34 left in regulation on a 1-yard touchdown by Brown. ECU kicker Kevin Miller missed a 32-yard field goal with five seconds left in regulation to send it into overtime.
SOUTHERN MISS 20, UAB 13: James Walley scored the go-ahead touchdown on a 1-yard run with 11:27 left for the visiting Golden Eagles. Walley played in place of Derrick Nix, out with a leg injury, and ran for 100 yards on 27 carries.
UAB erased an early 10-0 deficit to tie it at 10 at halftime. The Blazers took a 13-10 lead on Nick Hayes' 29-yard field goal with 13:43 left.
Southern Miss, behind reserve quarterback Micky D'Angelo, came back to score on a five-play, 80-yard drive. D'Angelo completed two big passes in the drive, a 35-yarder to LeRoy Handy and a 37-yarder to Chris Johnson. Walley's 1-yard run put the Golden Eagles in front 17-13.
AIR FORCE 49, ARMY 30: The visiting Falcons rushed for 380 yards, scored on nine of their 10 possessions and snapped a three-game losing streak.
Leotis Palmer ran for a score and threw for one on a halfback option pass for Air Force. Joey Ashcroft added field goals of 38, 38, 41 and 30 yards, setting a career high and tying a school record for a game.
Carlton Jones had touchdown runs of 4 and 2 yards for Army, which extended the nation's longest losing streak to nine.
