REGINA — The Saskatchewan Roughriders signed American offensive lineman Thaddeus Coleman to a two-year contract extension Thursday.

The deal keeps Coleman with the Riders through the 2019 season.

The six-foot-seven, 320-pound Coleman has spent five seasons in the CFL and two with the Riders. The 32-year-old started all 18 regular-season games, the East Division semfinal and conference final at right tackle last year.

He was named the Riders top offensive lineman in 2016.
