New York Giants defensive end Michael Strahan missed practice with back spasms yesterday and was listed as questionable for tomorrow night's game against the New Orleans Saints.

Strahan had the spasms Friday night and yesterday morning, and was treated by a chiropractor, the team said. He was replaced during practice by rookie Justin Tuck.

Strahan, the NFL's career sacks leader among active players, has experienced back spasms in previous years but they never have caused him to miss a game. He missed the last eight games of the 2004 season with a torn pectoral muscle.

* COLTS: Indianapolis defensive tackle Corey Simon participated in only 30 plays last week against Baltimore, but the difference the former Pro Bowler has made to the Colts may not be measured solely in statistics.

He's already added a small flat-screen television to the locker room, is quickly making friends and has created an attitude adjustment among the defensive players.

"We were excited to see the guys from the top take it to another level and get a guy that can really help us," safety Bob Sanders said.

Some players said they could already sense a difference in Baltimore's blocking schemes Sunday night, while others suggested having Simon in the lineup will give the team more opportunities to make big plays.

They couldn't ask for much more.

"Clearly, he made a difference and I think the Ravens thought he did, too," linebacker David Thornton said. "He's a difference-maker for us. He's a big body in the middle who allows linebackers to scrape a little more freely."

* JAGUARS: Byron Leftwich lined up at receiver several times against Seattle when Jacksonville used Matt Jones at quarterback in an opening-week victory.

The shift provided Leftwich and Seahawks cornerback Marcus Trufant a few good laughs, but it also made Leftwich consider the possibility of catching passes.

"All they have to do in situations like that is throw it to me, and I'll find a way to catch it," Leftwich said with a laugh. "I'd probably get tackled, but I'd like my chances of anything if they could get it to me."

* BENGALS: Come game day, Cincinnati right tackle Willie Anderson is very cool.

"You see him before the game and after the game, and he's got more bags of ice on him than anybody," quarterback Carson Palmer said. "He's got electricity stimulants hooked up to him. He's got three or four trainers working on him at one time."

That's what it takes to keep the Pro Bowl tackle on the field these days.

Anderson, 30, played much of last season with torn knee cartilage. He had surgery after the season, and was limited in what he could do during training camp. Nonetheless, he played the entire opener, a 27-13 win at Cleveland.

"Physically, I'm doing good," Anderson said. "It's going to be a while before I get that game-type conditioning and get my second wind in the game."

With Anderson holding his own, the line helped the Bengals run for 148 yards and throw for 272 against the Browns.
