New Baltimore Ravens coach John Harbaugh has said he plans to be tough on his players during off-season workouts and minicamps, and at the team’s practice today, the players were tough on each other.

Don Markus of the Baltimore Sun reports that there was a “knockdown drag-out midfield brawl” that started when offensive tackle Oniel Cousins and defensive tackle Amon Gordon “started flailing at each other at the end of a running play.”

The Associated Press reports that “nearly all 85 players got involved in a squabble” that started with Cousins and Gordon throwing punches at each other after running back Allen Patrick was tackled.  Per the AP, it took almost two minutes to break things up.

And that wasn’t the end of it:  defensive backs Corey Ivy and Frank Walker later came to blows during a blocking drill, the AP reports.

This isn’t the first time the Ravens have gotten physical with each other; tight end Quinn Sypniewski suffered a season-ending knee injury when he collided with linebacker Antwan Barnes in what was supposed to be a non-contact practice last month.

Said Harbaugh after today’s fights, “Guys are competing, so tempers flare a little bit.”
