Here's the article:
Miami Dolphins guard Richie Incognito, no stranger to altercations, was involved in another notable one before training camp.
After a late night at a nightclub in the Fountainbleu hotel in Miami, Incognito punched and knocked out a hotel security guard, according to league sources.
One person who knows Incognito says the Dolphins guard was punched first.
There is videotape of the incident but the hotel is unwilling to turn it over and the NFL has not yet seen it -- and might not due to fact that it is the hotel's property and the Fountainbleu prefers that attention not be brought to the issue.
The Dolphins have been aware of the incident because, as one source said, "they've done everything to bury it."
The NFL declined comment. The league knows it cannot police all altercations involving NFL players, though this one happened in public, with witnesses. It still is premature, but Incognito's altercation could be a violation of the NFL's personal conduct policy.
News of Incognito's confrontation comes in the same week in which Texans defensive end Antonio Smith was suspended one regular-season game for swinging his helmet at Incognito, a long-time rival. Their disagreements date back to when Smith and Incognito played in the NFC West, Smith for the Cardinals and Incognito for the Rams.
Cardinals players such as Smith and Darnell Dockett were known to dislike Incognito for the way he played. "They HATE each other," one person familiar with the two player's battles texted Tuesday. Smith felt as strongly as he did because he felt Incognito pinched players on the bottom of piles and delivered late hits when players weren't looking.
On Saturday night, a video replay of the incident shows Incognito sticking his hands under Smith's facemask, then shoving the Texans defensive end before Smith ripped off Incognito's helmet and swung it in anger, drawing the one-game suspension that the NFL announced today. Coaches who looked at the film said Incognito did nothing wrong on the play.
