"Kamar is a tough competitor and has shown he can be a consistent wide receiver in this league," Colts general manager Chris Ballard said in a statement. "He adds a nice complement to our wide receiver group and we look forward to watching him compete."

Aiken is a possession receiver who got pushed down the Ravens' depth chart last season.
In 2015, Aiken stepped up after Steve Smith suffered a season-ending injury and led the Ravens with 75 catches for 944 yards and five touchdowns. He also set a franchise record with nine straight games with at least five receptions.
