Michael Vick struggled in his first extended regular season action Sunday in the Falcons' 31-3 loss to Chicago. The No. 1 overall pick played the entire second half and was sacked six times and had a fumble returned 90 yards for a touchdown by Bears linebacker Brian Urlacher.

	Michael Vick fumbled on this play, with Brian Urlacher returning the fumble 90 yards for a touchdown.

Vick entered the game with the Falcons trailing 10-0. "I was put in a tough situation," Vick said. "That's what I'm here for. I've got to get out there and experience times like this."

Now, it seems as though Vick may have lost his hold on the No. 2 quarterback job in Atlanta. Coach Dan Reeves told the Atlanta Journal-Constitution that if Chris Chandler can't play Sunday, he isn't sure whether Vick or Doug Johnson would start.

Not only did Vick struggle on the field, he also had considerable trouble with the playbook. Vick, who had been operating with a limited number of plays in Atlanta's first two games, had far more information to process Sunday.

"We will look at it," Reeves told the paper. "If we feel like Doug would give us a better chance to get those things straight, then certainly we would have to consider that. We had about six plays that were called wrong."

One positive, Vick did complete 12 of 18 passes for 186 yards.

Each Tuesday from now until the end of the regular season, ESPN.com will hand out its report card on how the new kids are doing. Here's an update on some of the league's most intriguing efforts by rookies in Week 4:

PLAYER, STATS	THE SKINNY
Michael Bennett, RB, Vikings at Saints 8 att., 24 yds.	The Vikings continue to struggle to establish a running game. The Saints held the Vikings to 24 yards on 11 carries Sunday. Bennett, who was being counted on to ease the loss of Robert Smith, has yet to get on track this season. In four games he has rushed for 168 yards on 48 carries. While the rookie from Wisconsin has been effective as a receiver (16 catches), Minnesota needs to establish a consistent ground game.
Tommy Polley, LB, Rams at Lions 11 tackles	Polley, in his second game as a starter, was all over the field Monday night against the Lions. The second-round pick from Florida State recorded 11 tackles, including nine in the first half.
Anthony Thomas, RB, Bears at Falcons 11 att., 57 yds. 1 TD	The A-train got his first extended action of the season and was impressive, gaining 57 yards on 11 carries, including a 32-yard touchdown in the fourth quarter. "It felt good to get in the flow of things," Thomas told the Chicago Sun-Times. "The more I play the better I am going to get." James Allen has struggled, meaning Thomas could begin seeing more carries. "He looked good running the ball," coach Dick Jauron told the paper. "His size is an advantage and he showed speed when he gets to the secondary. He'll be a tremendous player for us."
LaDainian Tomlinson, RB, Chargers at Browns 19 att., 102 yds., 1 TD	Tomlinson continues to pile up impressive numbers. The No. 5 overall pick went over the 100-yard mark Sunday for the third time in four games. He's also found the end zone six times, tied for first in the AFC with Curtis Martin. Tomlinson's 54-yard run in the third quarter was San Diego's longest since the final game of '99.
Chris Weinke, QB, Panthers at 49ers 29-for-47, 275 yds. 1 TD, 3 INTs	Weinke had an inconsistent game for Carolina, completing 29 of 47 for 275 yards and a touchdown. He also threw three interceptions, including one by 49ers cornerback Ahmed Plummer at the San Francisco 13 with two minutes left when the Panthers were still in the game. Weinke has thrown three touchdowns and four interceptions in his first four NFL games.
Jamie Winborn, LB, 49ers vs. Panthers 12 tackles	Winborn had a team-high 12 tackles in his first NFL start, despite having part of his cheek torn off when he was spiked in the first quarter. "I didn't know I was hurt," Winborn told The San Francisco Chronicle. "Then I went to the sidelines and took a drip of water and it leaked out. Guys kept saying, 'What happened to you?' "
