Dolphins, NFL start probe

MIAMI - The Miami Dolphins and the NFL are probing allegations of player misconduct made Sunday by representatives of Jonathan Martin, the second-year lineman who has left the team to receive help for emotional issues.

The announcement by the Dolphins came Sunday afternoon, and only a few hours after the team said the notion of wrongdoing was merely speculative. It was part of a busy day off for the team, one that included the posting of several tweets by offensive lineman Richie Incognito, who said he wants his name cleared after several reports linked him to the Martin matter.
