Ottawa Redblacks running back William Powell left the team's first pre-season tilt during their first offensive drive with an apparent leg injury. He will not return.

It was unclear exactly what happened to Powell, but the running back had to be helped from the field and wasn't putting any weight on his left leg.

The injury could be a blow to the Redblacks if Powell misses significant time after the 28-year-old impressed down the stretch last season.

In seven games with Ottawa last year Powell had 447 yards and two touchdowns on 76 carries.

Redblacks punter Ronnie Pfeffer also suffered an apparent injury to his left foot.
