Some Dolphins players wearing Kaepernick shirts
A handful of Miami Dolphins players are wearing black T-shirts supporting free agent quarterback Colin Kaepernick during pregame warm-ups.
The shirts have "#IMWITHKAP" written in bold white lettering on the front.
Kaepernick was the first athlete to refuse to stand during the national anthem as a protest. This season, no team has signed him, and some supporters believe NFL owners are avoiding him because of the controversy.
Among the players sporting the shirts before their game against the New York Jets are wide receiver Kenny Stills, running back Jay Ajayi and offensive linemen Laremy Tunsil and Ja'Wuan James. Stills, also a team captain, posted a photo on Twitter of himself wearing the shirt , along with the post: "In case you didn't know!"
