Pads are on and tempers are boiling over on Monday morning at a joint practice between the Giants and Lions in East Rutherford.

The fight broke out after the Giants laid a hit on Lions receiver Amon-Ra St. Brown after he caught a pass during practice.

The scrum appears to have only lasted a few seconds as both teams were quickly separated by coaches and moved to opposite sides of the field.

As Lions players moved to the opposite side of the field, Giants fans went wild as players began waving at the crowd.

Giants coach Brian Daboll was also furious at one point because the ball was knocked out of Daniel Jones’ hands during the joint practice, and he did not want the quarterback to be touched.

The two teams will square off in the preseason opener on Thursday night at MetLife Stadium.
