A Roundup of the Week Oct. 1-7

PRO FOOTBALL—The Houston defense shot itself in the foot by calling timeout just before a play on which the 49ers would turn over the ball. On the replay of that down, Joe Montana completed a 46-yard touchdown pass to John Taylor that gave NFC West-leading San Francisco a 24-21 win and a 4-0 record. Falcon quarterback Chris Miller completed four passes to Andre Rison for 77 yards on one drive, including a three-yarder that cinched a 28-27 win over the Saints. The Colts upset the Chiefs 23-19 on Albert Bentley's second TD run of the game, a 10-yarder with 5:53 to play. The 4-1 Dolphins took a share of the AFC East lead with the Bills, thanks in good measure to Mark Duper, who caught 69-yard and 13-yard touchdown passes from Dan Marino to rally Miami from a 13-point half-time deficit to a 20-16 win over the Jets. The Lions beat the Vikings 34-27 as Barry Sanders rushed for 82 yards on 15 carries and caught three passes for 42 yards, including a 22-yard TD toss. With their second victory of the season, a 14-10 defeat of the Bucs, the 2-3 Cowboys doubled their win total of last season. Dallas was the only team from the NFC East to play; the Giants lead the division with a 4-0 record. In other games, the Bears, who lead the NFC Central, beat the Packers 27-13; the Bills knocked the Raiders, pacesetters in the AFC West, from the ranks of the unbeaten with a 38-24 triumph; the Seahawks, who beat the Bengals 31-16 on Monday night, crunched the Patriots 33-20; the Steelers stopped the Chargers 36-14; and Cincinnati, tops in the AFC Central, defeated the Rams 34-31 (page 38).

HOCKEY—With the Penguins' high-scoring Mario Lemieux busy convalescing from back surgery for three months, the best Lemieux in the Patrick Division as the season began was the Devils' Claude, who was recently acquired from the Canadiens. He scored two goals in New Jersey's 3-3 tie with the Red Wings and another in a 3-1 victory over the Flyers. Pittsburgh, even sans Mario, bettered New Jersey 7-4 on Sunday night to take over the top spot in the division. Forward Dave Poulin scored the Bruins' first goal of the season, 13:26 into Boston's opening-game 4-1 defeat of the Flyers, and then scored first in a 7-1 drubbing of the Nordiques, which put Boston ahead in the Adams Division. The Flames took the lead in the Smythe Division, with Gary Suter playing the starring role. He assisted on six of the seven Calgary goals in wins over the Canucks (3-2 in overtime) and Toronto (4-1). Despite being embarrassed by a charge of drunk driving two days before the season opener, Blackhawk coach and general manager Mike Keenan guided Chicago to wins over the Rangers (4-3) and the Blues (5-2), and into first place in the Norris Division.
