The video of B.C. Lions defensive halfback Stanley Franks’ knee bending at an impossible angle was so stomach-turning Wally Buono could only watch it once.

“It’s very ugly,” the Lions coach and general manager said yesterday. “It’s sickening.”

Franks, a second-year Lion, was taken off the field on a cart and immediately taken to hospital, where he underwent surgery Friday night after suffering a catastrophic injury to his left knee late in B.C.’s 34-32 loss to the Calgary Stampeders. The 25-year-old from Long Beach, Calif., is expected to undergo more surgery in the next two weeks.

The injury happened when a Calgary receiver stepped on Franks’ foot. That caused his foot to lock into the ground and resulted in the knee folding opposite to the way it normally bends.

It’s unlikely Franks will return this CFL season, which means Buono will have to make some adjustments in his secondary when the 0-2 Lions face the 2-0 Edmonton Eskimos Saturday at Commonwealth Stadium.

“We are going to look within,” said Buono. “We do have guys that have played strong halfback.

It’s expected David Hyland will replace Franks.

In both of their losses, the Lions showed potential, but not enough consistency to win.

“We’ve played two very good teams,” sighed Buono. “At the end of the day we were 0-2.”
