Carl Bottenfield, injured in the fourth period Saturday in New Haven and taken off the field on a stretcher, returned to Cambridge yesterday morning and is now resting comfortably in him Kirkland House room.

Bottenfield suffered a slight concussion after a jarring tackle of a Yale back and was taken to Now Haven Hospital. He was released early yesterday morning, in good shape although feeling a little weak.

The fullback, a junior, has suffered two previous concussions in his football career and had been warned after a concussion in his freshman year that if anything further happened he would probably have to give up football.
