Manziel is on the Hamilton Tiger-Cats' negotiation list, giving them exclusive CFL rights to the quarterback. The league said Jones' actions "constitutes tampering and is in violation of CFL bylaws.''
In February, there were reports Saskatchewan worked out Manziel. The Riders denied the reports and the CFL said there's no evidence to suggest any workout took place.
The Riders were fined for violating league bylaws regarding players attending practice while on the CFL suspension list as well as the recruitment of a junior player.
Jones said the Riders accept the league's punishments.
"The Saskatchewan Roughriders have been notified of the league's decision and accept their disciplinary action,'' he said in a statement. "We have been forthcoming with the CFL office on any information they have requested.
