Undated (AP) _ On a day when Emmitt Smith was hobbling, other top players in the NFL were hurting.

Pro Bowl defensive end Neil Smith of Kansas City, special teams captain Steve Tasker of Buffalo and cornerback Todd Lyght of the Los Angeles Rams also were injured Sunday.

The injury to Emmitt Smith, however, attracted the most attention. The league's defending rushing champion bruised his right quadricep two minutes before halftime and did not play again in Dallas' 27-14 loss to Atlanta.

''I took a knee to the quad,'' he said. ''I'll take whatever treatment is necessary and see how it goes.''

The Cowboys' next game is Thanksgiving Day against Miami.

Neil Smith left the field after intercepting a pass in the first quarter and did not return in Kansas City's 19-17 loss to Chicago.

In the same game, Chiefs starting linebacker Jaime Fields broke his hand in warmups and did not play. Chicago running back Tim Worley hurt his knee in the first half and was held out for precautionary reasons.

Tasker got a charley horse on the first punt of the game between the Bills and Indianapolis. He made the tackle on the play, but did not come back in Buffalo's 23-9 win.

Also injured in the game was Roosevelt Potts, the Colts' leading rusher. He hurt his right hamstring on his first carry and was out the rest of the day.

Lyght, a starter in the Rams' secondary, twisted his right knee in warmups. An MRI taken at Anaheim Memorial Hospital detected cartilage damage, and Lyght will undergo arthroscopic surgery.

Rams receiver Todd Kinchen injured his left knee late in the first quater of a 10-6 win over Washington and may require surgery.

Philadelphia quarterback Ken O'Brien left with a sprained right thumb after completing just 4 of 12 passes for 36 yards in a 7-3 loss to the New York Giants.

The New York Jets were forced to revamp their offensive line in a 17-12 win over Cincinnati when tackle Siupeli Malamala pinched a nerve in his left arm and guard Dwayne White sprained his right ankle. The Bengals lost receiver Carl Pickens with a sprained left foot and rookie defensive end John Copeland with a sprained left knee.

In Cleveland, Najee Mustafaa of the Browns sustained a mild concussion when he collided with Houston's Haywood Jeffires in the first quarter. Mustafaa was helped off the field and taken to the Cleveland Clinic for further examination.

David Williams of the Oilers bruised his leg and was to be X-rayed after the team returned to Houston.

Denver lost tight end Reggie Johnson in the second quarter with a strained right hamstring and safety Dennis Smith with a left shoulder strain in a 37-13 win over Pittsburgh.
