The Colts acquired Davis before the season for a second- and conditional sixth-round pick. The condition on the sixth-round pick was that Davis play in 65 percent of the Colts' plays during the regular season, according to a league source.
But a sprained left knee sidelined him for enough of the season that Davis played just short of the 65 percent threshold and now the Dolphins only will get the Colts' second-round pick, according to sources.
Davis, 24, finished the season with 51 tackles and three interceptions. He has 12 interceptions in his four-year career.
