Negotiations between the Kansas City Chiefs and Miami Dolphins, who have interest in offensive tackle Branden Albert, hit a major snag when Albert's contract demands caught the Dolphins off guard.
Albert, 28, reportedly has asked for a deal in line with Houston Texans' left tackle Duane Brown (six years, $53 million).
The Chiefs used the franchise tag to retain Albert, who was an unrestricted free agent. Albert is unhappy he didn't receive a long-term deal and hasn't reported to offseason workouts.
The Dolphins have a vacancy at tackle. Longtime starter Jake Long signed with St. Louis, leaving Miami to consider sliding second-year right tackle Jonathan Martin to the blind side. Martin replaced Long at left tackle for the final month of the 2012 season.
Long was considered an injury risk because of his shoulder, but some of the same concerns apply to Albert. Albert was injured Nov. 18 and missed the rest of the season with back injury.
Miami holds the 42nd and 54th overall picks in the middle of the second round. Kansas City would reportedly trade Albert, who can make more than $9 million guaranteed under the terms of his one-year franchise tender, for a second-round pick.
Albert was the 15th overall pick in the 2008 draft. He has 71 career starts in five seasons with the Chiefs.
The Chiefs traded their original second-round pick to the San Francisco 49ers for quarterback Alex Smith.
