Coach Bob Margarita's Yardling football squad, hampered by injuries, will meet Brown's freshman team at 2 p.m. today on Soldiers Field.

Early in the week, the Crimson freshmen lost two linemen during a brief workout with the varsity eleven. Guard Herb Grossman and center Roger Vaglia both suffered broken ankles.

The freshmen, who have lost two straight, to Andover, 14 to 0, and against Worcester Academy, 13 to 0, have been concentrating on their offense in practice. The defensive line has continued to show strength, notably in a workout against the varsity.

Margarita plans to start Tim Anderson, newly-elected captain of the '55 team, at right guard. Phil Perera will open the game at left guard, and the rest of the line shapes up with Stan Pfahl and Bernie Kafka at tackles, Bob Corcoran and Joe Ross at the ends, and Bill Toohey, a defensive stand-out, at center. Paul Murphy will be the starting quarterback, with Frank White and Dave Bicks at the halfback positions, and Bob Albert at fullback.

So far, Margarita's policy of free substitution has failed to produce an effective attack. In two contests, the freshmen have not scored, due mainly to the lack of club speed and an effective pass combination.
