No. 2 Alabama was still celebrating Mark Ingram's second long touchdown run when coach Nick Saban told his star tailback to take the rest of the day off.

Ingram ran for 102 yards and TDs of 25 and 40 yards in the first 20 minutes, then happily yielded the stage while the Crimson Tide breezed to a 45-0 win over Chattanooga on Saturday.

"Just get in, get a good day's work, execute and have some success. Then let the other people get the playing time they deserve," Ingram said.

Yes, the Tide (11-0) did make it seem just that easy.

Alabama raced to a 35-0 halftime lead and showed no signs of a letdown ahead of games with rival Auburn and No. 1 Florida. That enabled the starters to take a break in the second half against the Mocs (6-5), although Ingram and the Tide still managed a few highlight-reel plays.

Javier Arenas set the SEC career record with his seventh punt return for a touchdown, sprinting 66 yards down the right sideline in the second quarter. He also had an interception.

Julio Jones caught a 44-yard pass and scored on a 19-yarder from Greg McElroy.

The stats were perhaps even more lopsided than the final score. The Tide had a 422-84 advantage in total yards, gained 313 on the ground and had five players with at least 60 yards rushing. They also had 26 first downs while holding Chattanooga to five.

It only seemed like a pressure-free game. Saban warned his team of the repercussions of a huge upset, even beyond their national title hopes.

"I told the players if we had lost this game today, there would be nothing else that would tarnish what you've accomplished more than that. You would someday be an NFL player in a Mercedes-Benz and roll your window down to talk to a pretty girl and she'd say, 'You lost to Chattanooga when you played at Alabama,'" Saban said. "Nobody would ever forget that one."

Instead, it'll be forgotten quickly with the Iron Bowl awaiting six days later.

This was the sixth time the Tide's defense had held an opponent to seven points or less this season, but the first shutout since last year's 36-0 win over Auburn.

"We played a good football team and I don't know if there was much we could have done to be better than this," said first-year Mocs coach Russ Huesman, who led a turnaround after a 1-11 season.

Ingram managed his sixth 100-yard effort of the last seven games despite carrying only 11 times. The Heisman Trophy candidate broke three tackles and had two defenders draped across his back at the end of the 25-yard touchdown run in the first quarter.

Then, Ingram zigzagged 40 yards for another score 5 minutes into the second quarter on his final carry. Then he headed to the sidelines and Saban told him he "was pretty much done."
