Taking the ball on a speed sweep to the right side, McCalebb stretched the field as he turned the corner and raced to the end zone only 32 seconds into the contest.
His previous long TD run came last year when he went the distance from 48 yards against Mississippi State.
McCalebb was happy to produce a long touchdown run. "The running backs hadn't had a long touchdown run in a while," he said. "It was good to get one. Blocking by the offensive line and wide receivers was the key. I would have never made that play without them."
With the Tigers' passing game clicking early, there weren't many carries to spread around except for Mario Fannin, who saw more action than he has after being limited by a shoulder injury and problems with fumbling. Fannin produced the second highest rushing game of his career with 89 yards on 10 carries, including a two-yard touchdown run. The senior's previous high was 103 yards against New Mexico State his freshman season.
McCalebb finished the game with four carries for 62 yards as Auburn substituted heavily in its fifth victory of the season without a loss.
In other news and notes:

McCalebb's 50-yard run to open scoring capped a two-play, 65 yards drive that took only 32 seconds. Emory Blake's school record 94-yard touchdown pass from Cam Newton culminated a two-play, 97 yard march that consumed 42 seconds.
*McCalebb's 50-yard TD run was his longest run of the season and surpassed his career long touchdown run of 48 yards he had last year as freshman against Mississippi State.
*Cameron Newton entered the ULM game as the SEC's leading rusher at 121.2 yards a game. He carried the ball only once and that was on a sack that lost 11 yards. However, by the half Newton has topped his previous passing high of 203 yards against Clemson.
Newton totaled 231 yards with two touchdowns on 11 of 14 passing in the first half. Newton added a third touchdown pass covering five yards midway through the third quarter to Philip Lutzenkirchen before turning quarterback duties over to Barrett Trotter and Clint Moseley. Newton finished 14 of 19 passing for 245 yards. He made a poor throw Terrell Zachery near the goal line to suffer his only interception.
*Newton has 12 touchdown passes and four interceptions on the season. He added to his record of having two or more touchdown passes in the most consecutive games to start his Auburn career. The record is now five games.
*Auburn played virtually every healthy player on Saturday, but a reserve who did not see action was Jay Wisner who wasn't with the team for undisclosed personal reasons.
*Auburn entered the ULM game as the only team in the nation with three players averaging 70 or more yards rushing per game in Newton, McCalebb and Michael Dyer. None of them neared their averages with limited carries. McCalebb ran only four times, averaging 14 yards an attempt for 56 yards. Dyer had only seven attempts for 22 yards and Newton's 11-yard sack was his only rushing play.
