The Toronto Argonauts added some depth at receiver on Wednesday, getting former NFL player Patrick Johnson from the Edmonton Eskimos in exchange for a 2008 second-round draft choice.

The trade came after the Argonauts failed to come to terms on a contract with offensive lineman Glen Carson, who was acquired from the Eskimos in January.

The deal stipulated that if Carson didn't report to the Argonauts' training camp, Toronto received Edmonton's 2008 second-round pick, which they sent back Wednesday in exchange for Johnson.

The Argos retain the rights to Carson, who decided to sit out the year so he could return to the University of Saskatchewan in the fall to complete his degree in geophysics.

Johnson, 30, was signed by the Eskimos in late May. The five-foot-11, 191-pound native of Gainesville, Ga., was originally drafted by the Baltimore Ravens in 1999. He has also played for Jacksonville, Washington and Cincinnati.

In 70 career NFL games, he has 84 catches for 1,286 yards and 10 touchdowns.
