Malcolm Kelly caught a short pass, amid two defenders, and was stopped short of the sidelines.

Players casually went back to their huddles--to the chagrin of head coach Jim Zorn.

From 20 yards away, Zorn shouted, "Let's go! Come on, let's go!"

No time to waste. This was the 2-minute drill.

Zorn regularly pushes practice tempo, but when it comes to the 2-minute drill, he wants an even faster pace.

"It was our first go at it, just to get some of the mechanics down," Zorn said.

It's safe to say the defense is ahead of the offense at this point of the offseason.

On a pair of 2-minute drives, the Redskins' first-team offense could not score against the first-team defense.

"We would have loved to put it in [the end zone], but I was also glad we could keep it out," Zorn said. "A head coach has mixed emotions when you're in the 2-minute drill."

The only score of the extended practice session came from the third-team offense, with Colt Brennan completing a pass to a well-covered Marko Mitchell in the end zone for a touchdown.

Zorn said that the team's familiarity with his practice tempo and knowledge of the scheme has allowed coaches to get ahead in terms of installations.

He believes the coaches have implemented at least 30 percent more than they did at the same point last year.

In some respects, the OTA sessions are like training camp without pads and without the hitting, Zorn said.

"There is a little more teaching involved in each section rather than trying to create the intensity and competition," Zorn said.

-- WILLIAMS INJURED

Mike Williams suffered what appeared to be a knee injury during Monday's OTA practice.

"He went to the ground one time on a block and jammed his knee into the ground," Jim Zorn said. "It was just sore."

Williams has been seeing increased action during OTAs as he continues to reduce his weight to under 380 pounds.

Added Zorn: "It was a lot of beef to put on the ground so suddenly. We just took him off the field. I think he's going to be fine."

-- OTA ABSENCES

Rookie Cody Glenn missed Monday's OTA practice after his return flight back to Washington, D.C., on Sunday night was canceled.

"I don't know where he was, but he was in remorse that he could not be here," Jim Zorn said. "He'll get it together. There's no fine. Zero fine."

Albert Haynesworth and Anthony Montgomery were excused from Monday's practice, Zorn added.

Zorn expects Glenn, Haynesworth and Montgomery to be back at practice on Tuesday.
