First practice down...

Who knows how many to go.

Some observations:

* Troy Williamson dropped a pass, but he immediately rebounded, and he actually made a very tough diving catch on Cedric Griffin during seven-on-seven drills.

* With Sidney Rice still unsigned, fifth-round pick Aundrae Allison served as the third receiver and did a solid job.

* Chad Greenway wasn't held back at weakside linebacker, and E.J. Henderson looked very comfortable in the middle, shutting down an inside run attempt by Chester Taylor.

* It was apparent that Bryant McKinnie wasn't out there at left tackle, and coach Brad Childress didn't provide an estimated time of return.

* Childress on Rice and Adrian Peterson missing the first practice: "Those turns are important, and there is a point where you can't make up for those. And my best advice to them would be to get their tails in camp."
