However, Hartline has now claimed that Martin at first 'laughed off' a voicemail message from Incognito, which he later used against him to get him suspended from the team.
Hartline told NFL.com: "Martin was laughing about this voicemail at one point in time, first of all. Secondly, I believe that if you look through the whole voice mail, there's some things said that you probably shouldn't say in general, friends or not friends.
"But I know for a fact, that I've said things to my friends that I kind of wish I've never said to, either."
Hartline and Martin have been teammates since the latter arrived in Miami following the 2012 NFL Draft.
