Dolphins guard Richie Incognito is back on Twitter to apologize for his actions over the past week.

On Feb. 12, Incognito took to Twitter to lash out former teammate Jonathan Martin, who alleges he was bullied by Incognito.

In one tweet, Incognito addressed Martin: "The truth is going to bury you and your entire 'camp.' You could have told the truth the entire time."
