Receiver Jamel Richardson's move to Toronto may have hit a stumbling block.
Acording to Herb Zurkowsky of the Montreal Gazette, sources say Richardson failed his physical with the Argonauts on Wednesday.
Ricahrdson was released by the Montreal Alouettes last week after it was expected he would miss half the season while he continues to recover from a knee injury suffered last year.
A 10-year veteran, Richardson surpassed 1,000 yards receiving in five of his six seasons in Montreal. The 32-year-old had just 18 catches for 197 yards last season but missed 13 games due to injury.
