You may recall — or maybe you've tried to forget — that Incognito allegedly harassed Martin so much that the offensive tackle left the team. An NFL report concluded that Incognito and two other Dolphins "engaged in a pattern of harassment" against Martin. Not surprisingly, Martin apparently didn't respond to the tweets.
Earlier this month, Martin was traded to the San Francisco 49ers. Incognito is still looking for a team, with chatter connecting him as a possible member of the Oakland Raiders, whose owner, Mark Davis, told ESPN he would "have to think about" signing the controversial guard.
