NFC EAST

Dallas (10-5) and Philadelphia (10-5) have clinched at least wild card spots, with the division title at stake Sunday. If the Redskins (10-5) beat Dallas Sunday and the Eagles lose at Houston, Washington wins the division; if both the Eagles and Redskins win Sunday, the Redskins still would win the division on the basis of net points (differential between points scored and given up) in division games.If Dallas and Philadelphia win Sunday, the Cowboys win the division title because of a better conference record than the Eagles.

If the Redskins lose Sunday and Chicago, 9-6, defeat St. Louis, the Redskins and Bears would be 10-6 and the final NFC wild-card spot would be decided by net points in all games (the Redskins have a net 54; the Bears 21). Unless Tampa Bay (9-6) also loses. If that happens, the wild card berth goes to Washington. NFC CENTRAL

Tampa Bay, a 23-7 loser to San Francisco yesterday, can still win the division if it beats Kansas City no matter what the Bears do (Tampa has a better division record). But if the Buccaneers lose to the Chiefs and the Bears beat the Cardinals, Chicago wins the division by a game and Tampa goes home for the holidays. It can not be a wild-card team. NFL WEST

Los Angeles, 9-6, won NFC West, by beating Atlanta, 34-13, yesterday. AFC EAST

Miami, 10-5, won AFC East with 28-10 win over Detroit yesterday while New England, 8-7, was losing, 27-26, to New York Jets. AFC CENTRAL

Pittsburgh (11-3) can clinch title by defeating Houston (10-4) tonight. Cleveland's (9-6) 19-14 loss to Oakland (9-6) assures Steelers and Oilers of at lease wild card berths. If Pittsburgh and Houston finish with 12-4 records, deadlock would be broken on a basis of net points in division games (Pittsburgh has a net 46, Houston 17). AFC WEST

San Diego (11-4) and Denver (10-5) play for division title next Monday night because a Bronco win would give them the same record as the Chargers and a two-game sweep of the series. San Diego gets wild-card spot regardless; but if the Chargers beat Denver, Oakland and Cleveland would still be in the running with Denver for the remaining AFC wild-card spot.
