TORONTO — The Toronto Argonauts signed Canadian offensive lineman Corey Watman to a contact extension through the 2018 season on Thursday.

The six-foot-two 315-pound native of Queensville, Ont., played in 15 games for the Argonauts last season.

He signed with the CFL club as a free agent last February after spending three seasons with the Saskatchewan Roughriders.

Watman was the fourth overall pick in the 2013 CFL Draft.
