"A confrontation between Minnesota Vikings coach Brad Childress and receiver Percy Harvin grew so heated Friday afternoon that coaches and players were forced to separate them to prevent a physical exchange, according to team sources.

The confrontation, which was first reported by The (Minneapolis) Star Tribune as a heated argument between the two, occurred during a light Friday afternoon practice, Harvin's first of the week after suffering a sprained ankle last Sunday against the New England Patriots. Harvin was seen limping badly during the portion of practice open to reporters."
