A Roundup of The Week Oct. 3-9

PRO FOOTBALL—The Seahawks, leaders in the AFC West, defeated the Browns 16-10, but the worst news for Cleveland was that for the third time this season it lost a quarterback to injury. The latest victim was Mike Pagel, who separated his right shoulder while making a tackle after a blocked Browns field goal attempt. All Seattle's points followed Cleveland turnovers. The Bills ran their record to 5-1 and stayed atop the AFC East with a 34-23 victory over the Colts. Buffalo's Jim Kelly, who had thrown only two TD passes this season, connected with Andre Reed for two and Ronnie Harmon for one as the Bills overcame a 17-point deficit. Reed had seven catches for 124 yards. The Bears coasted to a 24-7 win over the Lions to remain No. 1 in the NFC Central with a 5-1 record. The Vikings' Anthony Carter caught seven passes for 82 yards and one TD as Minnesota defeated the Buccaneers 14-13 to remain one game behind the Bears. The Redskins dropped the Cowboys into last place in the NFC East with a 35-17 win; Washington quarterback Mark Rypien threw three touchdown passes and ran for another score. Surprising Phoenix, now 4-2, took the NFC East lead by burying the Steelers 31-14 behind Neil Lomax's 291 yards and three TD passes. In the NFC West the Saints, who began the week with a 20-17 Monday night squeaker over the Cowboys, on Sunday beat the Chargers 23-17 for their fifth straight victory, and the Rams defeated the Falcons 33-0 as Greg Bell ran for 155 yards. Thus, New Orleans and Los Angeles stayed tied for the division lead at 5-1. The 49ers dropped a game behind with a 16-13 overtime loss to the Broncos. The Packers got their first victory of the season with a 45-3 trouncing of the Patriots: the Oilers improved to 4-2 with a 7-6 win over the Chiefs; and the Dolphins beat the Raiders 24-14.

The NHL champion Oilers proved they could play without the Great One as they blitzed the Islanders 5-1 and beat the Jets 5-4. The Bruins hung their Wales Conference championship banner before their opener and then took an early lead in the Adams Division with a 2-1 win over the Maple Leafs and two triumphs over the Whalers by 6-2 and 3-1 scores.
