RENTON — Tarvaris Jackson began Sunday's scrimmage the same way he started training camp: Taking snaps with the first-unit offense.

All part of the plan, said coach Pete Carroll. And while no one has been named starting quarterback, Jackson's role in Sunday's simulated game spoke for itself.

"He's working with the first unit," Carroll said. "I can't make it any more obvious than that."

The scrimmage consisted of 80 plays, and while players were in pads and uniform pants, there was no tackling as plays stopped at first contact with the ball carrier. There was even an ejection, as rookie cornerback Jeremy Lane was tossed out after a skirmish with receiver Ben Obomanu.

The players have Monday off, and Carroll promised clarity on this week's quarterback plans once they return Tuesday. Seattle plays its first exhibition game Saturday against Tennessee, and Carroll indicated he'll soon share his plan at quarterback for that game.

"We'll come back on Tuesday and set it in motion," Carroll said. "We'll let you know how that goes when we get there."

Jackson completed four passes on 12 attempts during his time with the first-unit during the scrimmage. He was sacked twice.

Matt Flynn worked with the second-unit offense, and his first throw of the scrimmage was a 36-yard completion to Kris Durham, who leaped up to make the catch and fell hard on his hip. He didn't return to the scrimmage.

Flynn completed nine of his 20 passes. He was the only quarterback to pass for a touchdown — throwing to tight end Cooper Helfet. He was also the only quarterback to be intercepted as he was picked off in the end zone by linebacker Mike Morgan on fourth-and-goal.

Rookie Russell Wilson played with the third-unit offense. He completed nine of his 15 passes, the highest completion percentage of the three quarterbacks. He was also the only quarterback who didn't lead a touchdown drive, though he did drive the team into field-goal position on a hurry-up drive in the final minute of the first half.

"I'm really anxious to see the film," Carroll said. "See what it tells me."

Running back Marshawn Lynch had the longest play of the scrimmage, a 70-yard run in which he burst untouched through the line. It appeared Lynch was going to score, but rookie defensive end Bruce Irvin caught up to him at the 10-yard line.

Quarterback was the most scrutinized position of Sunday's scrimmage. Up until Sunday, the Seahawks alternated daily which quarterback worked with the first unit. According to that rotation, Jackson worked with the first-unit offense on Saturday, but the presumption that Flynn was next turned out to be wrong. Carroll said he planned for Jackson to be with the first unit at the scrimmage.

"There's a plan in mind here," Carroll said of Jackson's role with the first-unit. "It was exactly right. His turn."

Jackson said he didn't know until Sunday he would be with the first unit. Each quarterback got five series.

"It really didn't matter," Jackson said. "Obviously, you want to go with the ones, but whenever you get in with anybody else, you just want to make the best of it."

Notes

• Seattle released veteran receiver Antonio Bryant, who was trying to get back in the NFL after sitting out the last two years. Bryant was coming back from a knee injury, and had not practiced the past two days. Seattle signed kicker Carson Wiggs to take Bryant's spot on the roster.
