Defensive coordinator John Marshall said the plan is to start rookie Lawrence Jackson for the second straight exhibition game. Jackson started Saturday.

Jackson and veteran Darryl Tapp are competing for a starting job at defensive end.

Marshall also addressed questions about why the Seahawks blitzed Bears QB Rex Grossman so much early in the game, which seemed like a lot for a preseason contest. Marshall said the Seahawks were just "running their stuff" and didn't do anything out of the ordinary. Marshall felt Grossman had made the Seahawks pay in previous games, and didn't want him to get a rhythm right from the start.

The rain and threatening thunder and lightning sent everyone indoors. It felt like walking into another room inside a building.

The crown jewel of the Seahawks' new HQ is the indoor field, and certainly one big reason the team built the facility. The indoor field already justifies the building of the facility, because it was needed on the day of the first official team practice there.

After walking through the glass door to wacth practice, it was just another day. For the most part. C Chris Spencer practiced for the first time since the first day of camp in Kirkland. He said his back pain subsided enough for him to take part. Spencer did not take part in team drills.

DE Patrick Kerney and QB Matt Hasselbeck did, however. Hasselbeck didn't play in Saturday night's game to get more rest for a sore back, but he said he expects to play next Monday when the Seahawks are in San Diego. And DB Jordan Babineaux took part in his first full practice since hurting his knee in the scrimmage Aug. 2.

Coach Mike Holmgren said RT Sean Locklear has a sprained ligament in his left knee and that it will require rest, not surgery. He still hopes Locklear will be back in time for the first games.

Holmgren also said that after looking at the film from Saturday's game, he feels worse about what he saw. Maybe that's the reason he lit into his players during and after practice this morning.

"We played a horribly sloppy game," Holmgren said. "We gained 500 yards, the other team gets 200 yards [It was actually 431 to 205] and you're in an overtime game? How does that compute? Well it computes because you have six turnovers [including two blocked punts], 12 penalties...it was horrible, and I won't stand for it. Coaches or players. We gotta get crankin' again. It was too much 'at the playground' the other night."

One more thing -- backup QB Seneca Wallace was held out of practice with tightness in his groin, but will be OK, Holmgren said.

Practice is just beginning here in Renton at the new HQ, and No. 1 center Chris Spencer is out on the field stretching. That means he could be practicing today for the first time since the first day of camp.

The team started practice outdoors, but threatening skies caused them to abandon that and move indoors. Well, that's why they built this place, right?
