The Toronto Argonauts shored up its defence Thursday by inking defensive end Jonathan Brown to a contract extension.

The American-born Brown joined the club last year and had a strong 2004 campaign, finishing second on the team in sacks with eight. He also played a major role in Toronto's 27-19 Grey Cup win over the B.C. Lions by recording five tackles.

"I'm really glad to be back with the 'family' and keep everyone together," Brown said in a statement. "I didn't want to go anywhere else and now we have a chance to win back-to-back championships."

Brown is the latest member of last year's championship team to commit his future to the Argos. Thus far in the off-season, Toronto re-signed free-agent quarterback Damon Allen, linebacker Kevin Eiben, cornerback Adrion Smith and offensive linemen John Feugill.

The Argos have also given contract extensions to receivers R. Jay Soward, Arland Bruce III, Tony Miles and Robert Baker, defensive back Jordan Younger, kick-returner Bashir Levingston and offensive lineman Bernard Williams.

Also on Thursday, the Calgary Stampeders signed defensive back Jacoby Shepherd.

Shepherd attended the Edmonton Eskimos training camp earlier this year and spent the previous two seasons bouncing around the NFL.
