Officials have provoked Cincinnati Bengals linebacker Vontaze Burfict at least three times in the past month, according to a teammate who came to Burfict's defense Monday.

The Bengals player said he has heard officials cursing at Burfict on multiple occasions, and there is video that shows officials coming into contact with the linebacker three times in the past four games.

An NFL spokesman denied those charges Monday, saying it is not unusual for officials to come into contact with players and that there has been nothing unusual involving officials' interactions with Burfict.

But over the past month, according to a source close to Burfict, the Bengals linebacker has grown increasingly upset with officials' treatment of him and feels he is being singled out by officials.
