Saskatchewan acquired Watson from the Winnipeg Blue Bombers on Jan. 29. The former Concordia star spent five seasons in Manitoba, registering 178 receptions for 2,217 yards and six TDs in 67 career games.
Edmonton selected Saskatoon native Hus in the fourth round (31st overall) of the 2013 CFL Canadian Draft out of the University of Regina. He then signed with the NFL's St. Louis Rams, spending the 2013 and 2014 training camps with the team.
Hus also spent time with the Seattle Seahawks and Kansas City before being released by the Chiefs last week.
