Percy Harvin, Coach Brad Childress Argue on Field: Trouble for Minnesota Vikings

Brad Childress and the Minnesota Vikings continue to see their season spiral out of control.

The team has gotten off to a slow start at 2-5, with a banged up quarterback and a disappointing defense. Last week, the team released Randy Moss after four games, and almost saw their head coach fired in the same week.

Now, more controversy is brewing, with Brad Childress being the headline once again. This time, it involves him getting into a heated argument with another Vikings receiver.

According to Judd Zugland of the Minneapolis Star Tribune, Brad Childress got into an argument with Percy Harvin during Friday's practice. The report states that Childress questioned Harvin's effort this season, creating a darker cloud around the team.

The relationship between Childress and Harvin has already been shaky, so it isn't surprising. As FanHouse.com noted, Harvin was "livid" over Childress' decision to release Moss.

It seems that Brad Childress is fighting to save his job the rest of the season, and so far his players are on his bad side.

The Vikings are in a must win situation against the Cardinals this week. Another loss could lead to more speculation about Childress' job security in the upcoming weeks.
