McQuarters is currently competing with Jerry Azumah for the right to start opposite Charles Tillman. At this point Azumah has the inside track, but this likely won't be settled until the end of the preseason.
On the following play Grossman had his pass deflected at the line of scrimmage and it hung in the air long enough for Brian Urlacher to run under it for an interception he returned for a touchdown.
The Bears have been working diligently to create more turnovers as well as trying to move the ball forward when on an interception or fumble recovery.
The offensive and defensive line left practice early as the rest of the team worked on punt coverage drills. At one point McQuarters fielded a punt and threw a lateral across the field to Bobby Wade. Although the play didn't result in a huge gain, it does show that special teams coach Dave Toub is willing to take a risk for a shot at a big play.
The Bears have one practice on Wednesday and Thursday before getting a break until the middle of next week.
