Coach Mike Shanahan said quarterback John Beck’s groin remains sore but is getting better. The coach said helping Beck from the competition standpoint is the fact that he took a week’s worth of snaps before Rex Grossman arrived, so coaches have been able to see him. Shanahan still doesn’t have an idea of whether Beck, who still can’t sprint to his right or left without pain, will be able to play Friday.

Artis Hicks sat with a slight concussion, Shanahan said.

Shanahan said he is pleased with the progress the five new defensive starters are making, and says he sees improvement in chemistry already.

Tim Hightower has now fumbled in four of his five practices with the team. The running back’s latest fumble came at the goal line.

Duking it out for the kicking job, Graham Gano and Shayne Graham attempted field goals during the scrimmage portion of practice. Gano made six of seven, with his longest from roughly 56 yards out. Graham was 5-for-7 with a long of 46.

Rookie linebacker Ryan Kerrigan admits his pass coverage skills are still in the developmental stage. But Tuesday he made a nice play on the ball, breaking up a pass intended for tight end Logan Paulsen in the back of the end zone.

Rookie wideout Leonard Hankerson has had his ups and downs during camp, but it’s clear his big hands and leaping ability will come in handy, particularly in the red zone, where he made an impressive grab in the back corner and got two toes down for the completion.

Cornerback DeAngelo Hall stretched and snagged a ball in the end zone with one hand. Safety LaRon Landry turned and said, “He got them Mickey Mouse hands. Big ol’ hands, man.”

Kellen Clemens had a pair of interceptions during today’s scrimmage - one to Chris Horton and one to Dante Barnes.
