TORONTO - The Toronto Argonauts returned a key element of their offensive line while giving the lone remaining defensive starter from their 100th Grey Cup-winning squad an early start to free agency.

The Argos re-signed international offensive lineman Jarriel King to a contract extension Tuesday. King was scheduled to become a free agent Feb. 10.

So was defensive back Jalil Carter, who started last season as the lone returnee from the Toronto defence that anchored the club's 35-22 win over Calgary in the 100th Grey Cup game in 2012 at Rogers Centre. Carter joined the Argos in '12 and appeared in 34 regular-season games, two playoff contests and the historic championship encounter. He is expected to sign with the NFL's Minnesota Vikings this week.

King joined the Argos prior to the '13 season and started 13 games at right tackle as a rookie. He appeared in 11 contest, making nine starts, last year mostly at right guard.

"Jarriel brings a good combination of size and athleticism to our offensive line and he has shown his versatility by starting games at guard and tackle," GM Jim Barker said in a statement. "We look forward to watching him continue to develop with us in Toronto."
