IRVING, Texas – Brad Johnson signed a contract Monday night with the Dallas Cowboys, who wanted a veteran quarterback to team up with Tony Romo.

Johnson’s agent, Phil Williams, said the quarterback got a three-year contract. Williams wouldn’t discuss financial details of the deal.

Cowboys officials didn’t respond to messages Monday night, and the team had not announced the deal. On their Web site, the Cowboys reported they were “close to adding” Johnson to the roster.

The 38-year-old Johnson became an unrestricted free agent last week when the Minnesota Vikings, in a long-expected move, released the 15-year veteran. Johnson won a Super Bowl with Tampa Bay after the 2002 season.

Dolphins release Harrington, McMichael

MIAMI – Quarterback Joey Harrington and tight end Randy McMichael were released Monday by the Miami Dolphins.

Miami also signed tight end David Martin to a three-year contract. Martin had 87 receptions for 766 yards and nine touchdowns in six seasons with Green Bay. He caught 21 passes last season and scored a touchdown against Miami.

The release of Harrington had been expected, in part because he was due a $1 million roster bonus. In his only season with Miami, he went 5-6 as a starter filling in for Daunte Culpepper, then was benched the final game in favor of Cleo Lemon. McMichael was due a $3 million roster bonus, and his contract was terminated after Miami was unable to swing a trade for him.
