The dominos continue to fall in the AFC West.

A day after the Denver Broncos snared star slot receiver Wes Welker, the Kansas City Chiefs countered by signing one of the best cornerbacks available in free agency, former Miami Dolphin Sean Smith.

The 25-year-old Smith agreed to a three-year deal, confirmed by his agent David Canter on Twitter.

A former second-round pick out of Utah, Smith leaves South Florida after recording two interceptions in each of the past two seasons.

He joins Brandon Flowers and fellow free agent pickup Dunta Robinson to form an impressive trio of corners for new Chiefs head coach Andy Reid, one which hopes to match up with the talented triumvirate of receivers Denver has in Welker, Demaryius Thomas and Eric Decker.
