Chad, Madieu tangle twice

The Bengals made it to the second-to-the-last day of training camp before tempers flared.

Safety Madieu Williams and wide receiver Chad Johnson exchanged punches in two different incidents during the afternoon practice. It is scheduled to run until 5 p.m.

Early in practice, Johnson and Williams appeared to trade words during a drill. Johnson flung the ball at Williams as he walked away.

Later, in 11-on-11 team drills, Johnson and Williams tangled again at the end of a play. Coach Marvin Lewis was among those who broke up the fight, during which both players lost their helmets and threw punches.

Then, on a deep pass play from Carson Palmer to Johnson, safety Dexter Jackson intercepted near the goal line. Williams shoved Johnson to block him. They again traded blows, with Johnson's helmet coming off.

Defensive backs coach Kevin Coyle and Jackson broke them up.
