HAA doctors predicted yesterday that the injury lineman Joe Busch suffered during Saturday's intra-squad football game "may cause repercussions" in the sporting world. Busch, a transfer student from Ames, lowa, walked off the field after a second-period line play with an eyeful of "Unbreakable" contact lens fragments.

Busch didn't know at the time that the lens had shattered. "Tell me if it's broken, Jimmy," he keep saying as trainer Jimmy Cox mopped the eye with wet towels. He found out 20 minutes later on the emergency operation table at Massachusetts General Eye and Ear Infirmary. It took surgeons two hours to pick particles of plastic out of Busch's left eye--and save his sight.

"It's a highly technical job," team doctors said yesterday, "and Mr. Busch can be thankful that the accident happened in a place like Boston, where there are men capable of handling operations of that type." Busch returns to Cambridge today, and his father, a doctor, has notified him that it's all right to continue with football if he wants to.

The medical authorities at Dillon Field House predict an investigation of contact lenses by the Coaches Association.
