Ottawa RedBlacks quarterback Trevor Harris is expected to miss "weeks" with a bruised throwing shoulder, but the injury isn't considered season-ending, head coach Rick Campbell told TSN1200 on Monday, via CFL.ca.

Harris, who leads the CFL in passing yards and touchdowns through 12 weeks, left Saturday's game against the Hamilton Tiger-Cats in the third quarter and was spotted with his arm in a sling after the contest.

Appreciate all the kind messages and people reaching out.. I'll heal up asap. we're going to get this done. I love this team! — Trevor Harris (@Trev_Harris) September 10, 2017

Drew Tate relieved Harris against the Tiger-Cats and will likely get the starting nod Sunday when the RedBlacks face the Montreal Alouettes.

Ottawa rests atop the East Division standings with a 4-7-1 record.
