OTTAWA — The Ottawa Redblacks will re-evaluate Trevor Harris on Friday after the quarterback was injured in the team's opening CFL pre-season game.

The 33-year-old Harris left in the first quarter of Ottawa's 27-7 win over the Montreal Alouettes on Thursday night. He suffered a lower leg injury, his left knee appearing to buckle after being hit by Alouettes linebacker Chris Ackie.

Harris was in obvious pain afterwards as he limped off the field with the assistance of medical staff. A visibly frustrated Harris went directly to the locker-room.

Harris didn't return to action, finishing 3-for-5 passing for 34 yards and one interception. He was replaced by Dominique Davis.

Harris was back on Ottawa's sideline in the second half and wasn't sporting either crutches or a walking cane.

Redblacks head coach Rick Campbell said after the game Harris's injury doesn't appear to be serious. Ottawa went 1-2 last season in the three games Harris missed with a shoulder injury.

Harris threw for 4,679 yards with 30 touchdowns and 11 interceptions last year.

Ottawa concludes its pre-season schedule Thursday night against the Toronto Argonauts in Guelph, Ont.

The Redblacks kick off the regular season June 21 against the visiting Saskatchewan Roughriders.
