The Cardinals, who lead the league in NFL regulars, parlayed a couple of fumble recoveries into touchdowns and downed the Saints 24-19.

HOCKEY—The 71st NHL season opened with a number of star players on the sidelines. Last year's Wales Conference champion Flyers were without MVP goalie Ron Hextall, suspended for eight games for a slashing incident in last year's finals. But rookie Mark Laforest filled in ably as the Flyers skated to a 2-2 tie with Montreal and a 5-4 win over Minnesota before dropping a game to Chicago 5-3. Minnesota had to make do without All-Star forward Dino Ciccarelli, who was serving a three-game suspension for a preseason altercation. The North Stars tied the Sabres 2-2 and lost to the Flyers. The Islanders fared well, beating Los Angeles 4-1 and Vancouver 7-1, even though their alltime scoring leader Mike Bossy is sitting out the year with an ailing back. The Nordiques, with 10 new players in the lineup and rookie coach Andre Savard behind the bench, were also unbeaten, as they rolled over the Whalers 5-1 and edged the Bruins 6-5 in OT. Edmonton, the Stanley Cup champion, began the season without defenseman Paul Coffey, who is in a contract dispute. The Oilers could have used him in a 4-1 loss to Detroit in their home opener. It was a bit of revenge for the Red Wings, who lost to the Oilers in last year's semifinals. Glenn Anderson got the Oilers back on track, scoring a hat trick in a 9-2 romp over the Kings.
