As expected, Canadian-born quarterback Tommy Denison was one of a dozen players released Monday by the Toronto Argonauts.

Denison, a two-time Hec Crighton Trophy winner from Beamsville, Ont., was thrown overboard by the Boatmen before the midnight ET deadline to reduce training-camp rosters to 50 players.

Toronto, the defending Grey Cup champion, also cut a trio of defensive backs in Raphaol Ball and rookies Derek Combs and Greg Golden.

"They both had some good moments Saturday night," Argos director of player personnel Greg Mohns said of Combs and Golden.

"But unfortunately, it's a numbers game because you can keep only so many Americans and we've got a lot of veterans back."

CFL teams begin the season with active rosters of 40 players – 19 Canadians, 18 Americans and three quarterbacks.

The Winnipeg Blue Bombers doled out walking papers to 13 players, among them receiver Dimitrius Breedlove and defensive backs Jayson Bray, Stephen Fisher and Markese Fitzgerald.

The Ottawa Renegades re-signed quarterback Darnell Kennedy before releasing 10 players, including defensive lineman Dimitrius Underwood, long snapper Steve Glenn and rookie running back Les Mullings.

"There was some rust there," Renegades general manager and head coach Joe Paopao said of Underwood, a former first-round pick in the NFL.

"We wanted to take a look at his potential at making an impact and felt we had seen enough."

The Calgary Stampeders cut nine players, including defensive back Lawrence Deck.

The Montreal Alouettes bid goodbye to five players, including former 1,000-yard receiver Darnell McDonald.

The Edmonton Eskimos lopped four players off their roster, notably long snapper Roger Reinson and rookie kicker Chris Brewer.
