PRO FOOTBALL—The Giants remained undefeated, at 4-0, by beating the Cowboys 30-13, as Phil Simms threw two touchdown passes and Raul Allegre kicked three field goals. Unruffled by seven sacks, the Steelers' Bubby Brister completed a team-record 15 straight passes on his way to 267 yards in the air, and Pittsburgh scored after four Detroit turnovers in crushing the winless Lions 23-3. Jim Kelly and Thurman Thomas teamed up to lead the Bills past the Patriots 31-10; Kelly threw three TD passes, including a 74-yarder to Thomas, and Thomas had 204 yards in total offense. Vinny Testaverde finished with only 82 yards passing, had 11 straight incompletes and was sacked twice as the Vikings upended the Bucs 17-3. The Colts had their "first touchdown" of the day called back twice and then, on their third try for the TD, threw an interception that Jet safety Erik McMillan ran back 92 yards for a score. But Indianapolis recovered from that shaky start to sack New York's Ken O'Brien five times, rally from a 10-point deficit and beat the Jets 17-10 on a 49-yard fourth-quarter punt return by Clarence Verdin. The Saints fell to the Redskins 16-14 as Washington's Chip Lohmiller made field goals of 48, 19 and 18 yards, and New Orleans's kicker, Morten Andersen, missed two, the second from 36 yards with 2:34 to play. Linebacker Leon White seemed to go unnoticed as he dug a fumble out of a pileup and raced 22 yards in the fourth quarter to give the Bengals a 21-17 victory over the Chiefs. In the Sept. 25 Monday-night game, Cincinnati beat the Browns 21-14. A holding penalty against Cardinals linebacker Ken Harvey early in the fourth quarter gave the Chargers, who trailed 13-7, a first down on the two, from which they scored a touchdown and launched a comeback that ended in a 24-13 win. The Raiders, who suffered their third consecutive loss, built a 17-7 lead in the first three quarters before falling to the Seahawks 24-20. In other games: The Oilers routed the Dolphins 39-7; the Packers rallied to beat the Falcons 23-21; the Rams remained unbeaten by spoiling the 49ers' perfect record 13-12; and Cleveland knocked off the Broncos 16-13 (page 36).
