Navy (1-6) at Tulane (5-3)

When: 3:30 p.m. Saturday.

Where: Louisiana Superdome, New Orleans.

The Matchup: Navy finally gets to play a team against which it will not have a significant size disadvantage. Tulane's left guard and left tackle average a Navy-like 266 pounds, and, like Navy, they have had trouble blocking, as star running back Mewelde Moore is averaging less than 3.5 yards per carry. The front four on Tulane's defensive line average 270 pounds. Many of the Green Wave's skill players, however, already have left an impression on the Midshipmen. In Tulane's 42-21 victory over Navy last year, Moore had more than 100 yards rushing and receiving -- the first player in the program's 110-year history to do so in the same game -- and junior free safety Lynaris Elpheage had a 48-yard interception return for a touchdown. Two years ago, in a 52-38 win over Navy, Elpheage had a 23-yard fumble recovery for a touchdown, recovered another fumble, broke up four passes and made seven tackles.

Behind the Scenes: Navy has had trouble at left guard. Starter Grant Moody is out indefinitely with a knee injury suffered against Rice two weeks ago. Backup Travis Peace, who started in a 46-21 loss to Boston College last week, left the game early with a knee injury. His backup, Brett Cochrane, also left the Boston College game with an injury, forcing fourth-string junior Sean Magee to play the position. Cochrane later returned to the game. There may, however, be help on the way for next year: The Naval Academy Prep School team has two 300-pound linemen and center Ryan Roeling, who is 6-feet-4 and 282 pounds and turned down a scholarship offer from Virginia to attend NAPS.
