The Arizona Cardinals worked out Canadian Football League standout pass rusher Alex Hall, according to a league source.
The Saskatchewan Roughriders defensive end wasn't immediately signed to a contract. He was traded to Saskatchewan from the Winnipeg Blue Bombers this season. He was named an East Division All-Star.
He worked out for the Minnesota Vikings in December.
A former Cleveland Browns seventh-round draft pick from St. Augustine's College, Hall has also played for the Philadelphia Eagles, Arizona Cardinals, and New York Giants.
The Vikings also worked out wide receivers Dontrelle Inman, Chris Matthews and Nick Moore and defensive tackle Ted Laurent.
