The Toronto Argonauts announced on Monday the signing of former NFL Pro Bowl wide receiver David Boston.
Boston, 29, spent six seasons in the NFL where he was known for his size and speed, but also for problems off the field.
The former Ohio State standout caught 315 passes for 4,699 yards and 25 touchdowns in the NFL, with Arizona, Miami and San Diego.
"We've been looking for a physical receiver and not only does David play physical but he has great speed," said Greg Mohns, the Argos assistant general manager. "His resumé speaks for itself."
Boston's peak years were with Arizona, where he caught 98 catches for 1,598 yards and eight touchdowns in 2001 to earn a spot in the Pro Bowl.
The six-foot-two, 225-pound receiver was injured much of the next year, and then opted to sign with San Diego in 2003. The Chargers traded him after just one season, during which he was suspended briefly by the team for disciplinary reasons.
At his next stop in Miami, Boston tore ligaments in his knee and received a four-game suspension from the NFL for testing positive for steroids.
While attempting a comeback with the Tampa Bay Buccaneers in August 2007, he was found passed out behind the wheel of his Range Rover in Pinellas Park, Fla.
He was charged with misdemeanour DUI and was let go the next month by Tampa Bay after a urinalysis taken at the time of the incident tested positive for GHB (gamma hydroxybutyrate), a drug sometimes used by bodybuilders.
"I'm extremely excited to come to Toronto and compete and hopefully win a Grey Cup championship," Boston said in a statement. "I'm thankful for the opportunity the organization has given me and I'm looking forward to being at training camp."
Toronto has revamped its offence for first-year coach Rich Stubler, acquiring last year's outstanding player in the league, Kerry Joseph, from the Saskatchewan Roughriders.
