Paul Perkins, the boy who made the Harlow T formation work last Saturday, will be on the sidelines tomorrow because of a leg injury, and with that news Tufts became an overwhelming favorite in its first visit to Soldiers Field.

With Perkins gone, Henry Lamar is without the team's most powerful plunger, best ball-handler, and best passer from the fullback slot. Paul Garrity, who will move over from tailback to replace him, is about 15 pounds lighter, and has had a year less at Harvard, which makes a big difference in performing the fullback's complicated duties.

In his place, Bill Henry will play left halfback, a post at which he has seen almost as much action and has been passing more effectively. George O'Day and Tow Ellis are the second-string fullback and tailback respectively.

The rest of the line-up remains unchanged, with Rod Perkins and Don Geeson at end, Jim Waterhouse and Bob Merrill, at tackle, Gibby King and Jed Goldberg at guard, Ed Donovan at cen- ter, Wally Trumbull at blocking back, and Dick Warren at wingback.

On the Tufts eleven, the two men to watch are Charlie Fortin and Chick Rutter. Wingback Fortin is the most powerful runner on the team and an excellent left-handed passer, while Rutter, the left half, is the Jumbos' best broken-field runner, as well as a deadly passer.

Sampson Outstanding

In the line, the outstanding players are Alan Sampson, the right end, who calls the plays; Captain George Sweeney right guard; and the two tackles, Weber and Lonergan. Tony DeTeso, former captain and center, left at midyears and his loss has forced Lew Manly to experiment.

Tomorrow's game may turn out to be a battle of double-shifts, or Victory Shifts as they are now called. Although Tufts hasn't used the play this year, the Jumbos did pull it in a scrimmage here two years ago, and Manly has said that he expected to fight fire with fire in case Harvard uses it, which Harvard is sure to do.

For the first time this year, Lamar will have the benefit of scout's reports, since he and Floyd Stahl have seen Tufts three times--at the pre-season scrimmage and at two games when the Crimson wasn't busy--and he has been able to conduct his practice sessions accordingly. Manly has had scouts at all Harvard games
