The CFL terminated the 2012 Heisman Trophy winner's contract with the Montreal Alouettes on Wednesday. The league also informed the eight other teams that it wouldn't register a contract for Manziel if any tried to sign him.
"We advised Montreal that Johnny had violated one of the conditions we had set for him to be in our league. And Montreal announced his release today," CFL Commissioner Randy Ambrosie said in Vancouver. "We didn't release the terms of those conditions then and we're not going to do that now.
"We're trying to do what we believe is in the best interests of the entire league.
