Huard, 30, is expected to join the Chiefs for a three-day minicamp that begins Friday. Details of the contract were not immediately available, but it is likely a deal at or near the league minimum of $660,000 for a seven-year veteran.
The addition of Huard bolsters a depth chart that includes starter Trent Green and No. 2 quarterback Todd Collins. Kansas City had lost its No. 3 quarterback, Jonathan Quinn, to the Chicago Bears earlier in the free agency signing period. There had been indications the team would seek another veteran and Huard observed recent on-field workouts in Kansas City without participating in them.
With a roster deep in talent, and coming off a 13-3 season, the Chiefs have been justifiably quiet in the free agent market.
Huard visited with several teams in free agency, most notably Green Bay and Atlanta, and it seemed only a matter of time until one of them signed him. Despite his inactivity in New England over the past three seasons, Huard is viewed as an able, experienced and savvy veteran who understands the backup role.
The former University of Washington star has appeared in 38 games, six of them starts, and has a 5-1 record as a starter. All of his starts were with the Miami Dolphins, five of them in 1999, when he replaced an injured Dan Marino.
Huard has completed 170 of 289 passes for 1,691 yards, with nine touchdown passes and eight interceptions, for a passer rating of 74.3. Huard hasn't started a game since 2000 and has appeared in only four games the past three seasons.
