PHILADELPHIA, JAN. 5 -- The Redskins won't know their second-round opponent until after Sunday's Bears-Saints game at Soldier Field, but this afternoon, after a 20-6 elimination of Philadelphia, they said it hardly mattered.

If the Bears win, the Redskins will play the San Francisco 49ers Saturday at Candlestick Park. If the Saints win, they'll play the Giants in the Meadowlands on Sunday. They're 0-2 against the Giants and 0-1 against the 49ers this season.

"Whoever it is, we'll have the same approach," running back Earnest Byner said. "We don't have any choice in the matter and they're both real good teams. We'll take a day to enjoy this one and watch someone else play, then we'll get down to business."

The 49ers defeated the Redskins 26-13 in Week 2 as Joe Montana passed for 390 yards. The Redskins are 2-5 against the 49ers since Gibbs arrived in 1981 and are winless in three games at Candlestick Park. They've lost six in a row to the Giants and nine out of 10 nonstrike games since 1985. Much Gain, Little Pain

It was a different kind of game for Redskins trainer Bubba Tyer, who'd spent about an hour on the field eight weeks ago in a 28-14 loss to the Eagles. Nine players were hurt that day and five were carried off the field, including Joe Howard, who was knocked cold.

But today Tyer didn't go on the field, and after the game had a short injury list. Mark Rypien and Byner suffered sprained ankles, but both are expected to practice this week.

Meanwhile, Gary Clark played the entire game with a sore knee and ankle, and Tyer saluted him.

"That guy is remarkable," Tyer said. "He has a swollen ankle and knee and has to be in pain, and he still gets out there and plays his fanny off. That's one tough guy. We came out of the game in good shape, but we did a lot of taping on the sideline to get guys back out there." Step It Up and Go

The Redskins scrambled to slip into different shoes early in the game after getting on the field and finding it damp. Rypien and others slipped around the field several times in the first half, and equipment managers hustled different shoes onto the sidelines. Players put them on between series, or in the locker room at halftime. . . .

The Redskins' unsung hero may have been punter Kelly Goodburn. He kicked nine times for a 36.9 average and dropped four punts inside the 20-yard line. . . . The Redskins sacked Randall Cunningham 15 times in three games this season. . . . The Eagles are 0-3 in the playoffs under Buddy Ryan, and haven't won a playoff game since defeating Dallas in the NFC championship game on Jan. 11, 1981. . . . The Eagles had won six in a row at the Vet.
