The Roughriders said Monday that Smith will miss the game against the Winnipeg Blue Bombers after the team learned he was "charged with violating a condition of release stemming from an incident last August."
Smith was charged with assault last August after he and teammate Dwight Anderson allegedly beat a man outside of a Regina nightclub.
A judge ordered Smith to stand trial after a preliminary hearing in June found that there was enough evidence to try him but not Anderson.
Evidence presented at a preliminary hearing is subject to a publication ban.
Smith has 227 receiving yards so far this season with two touchdowns.
