Incognito, Martin tweet support for Sam

Miami Dolphins teammates Richie Incognito and Jonathan Martin have spent the past 3½ months at the center of a national debate about hazing and the NFL's locker room culture.

Incognito and Martin each took to Twitter on Monday in support of Michael Sam, an All-American defensive lineman from Missouri who publicly acknowledged in an interview with ESPN's "Outside the Lines" on Sunday that he is gay.
