The Saskatchewan Roughriders have signed three Canadian free agents including Regina's Jordan Sisco.

Sisco will be entering his fourth season with the team. He played in the Riders' first seven regular season games last year before an injury forced him to miss the rest of the season.

The team also picked up defensive back Weldon Brown and lineback Tristan Black.

Brown comes to the Riders after three seasons with Edmonton.

In 13 starts for the Eskimos last season, Brown recorded 35 defensive tackles, a fumble return and a quarterback sack.

Black joins the Riders after playing for the three seasons in Toronto.

Originally drafted by the Calgary Stampeders in the second round of the CFL Canadian Draft, Black has dressed in 52 career regular season games and has recorded 17 defensive tackles and 50 special teams tackles.

Offensive lineman Alexander Krausnick-Groh and defensive back Chris McKenzie are the only Rider free agents who remain unsigned.
