LAKE FOREST, Ill. -- A brief skirmish broke out at Tuesday's organized team activity during a team drill between members of the Chicago Bears' starting offense and defense. Involved in the short-lived fracas was defensive end Lamarr Houston, right tackle Jordan Mills, tight end Martellus Bennett and defensive end Jared Allen.
Teammates quickly intervened to end the fight, but not before Bennett slammed his own helmet to the ground in frustration.
"We are just competing,” Houston said afterward. "This is a competitive sport. That's the atmosphere Coach Trestman wants. We are competing every day to get better. Sometimes people get heated, but all we are doing is competing out there. It's exciting out there. It's a competitive atmosphere. We're having fun in practice.
"That's football. We just go back to the next play and keep working. It's nothing personal. Marty is a good guy. He's a good friend of mine. I'm going to go in there with him after this. Everything is all good.”
Bennett later tweeted: "I go hard every [expletive] day. No doubt about that. Not a single ounce of [expletive] in me.”
Here are several other observations from Tuesday's voluntary session:
Middle linebacker D.J. Williams worked out in front of the media for the first time in the offseason. Williams was absent from last Tuesday's open OTA, but did participate in practices later in the week that were closed to the media.
Charles Tillman's absence on Tuesday opened the door for veteran cornerback Kelvin Hayden to receive a look on the first team at cornerback in the base defense and in the nickel package. Hayden missed the entire 2013 regular season after tearing his hamstring in training camp. Rookie first-round pick Kyle Fuller still worked with the starters in nickel when Tim Jennings bumped inside to cover the slot.
Hall of Famer Mike Ditka watched Tuesday's workout from the sidelines in Lake Forest. Ditka addressed the team last year following a practice at Halas Hall, and had his number retired by the Bears during halftime of the team's Monday night Dec. 9 game versus the Dallas Cowboys at Soldier Field.
Wide receiver Alshon Jeffery flashed his strong hands when he went up and snagged a red-zone pass over Jennings.
