Cornerback Darrell Green did not practice yesterday because of soreness in his legs, but he and Redskins Coach Joe Gibbs said he is expected to start Sunday against the Philadelphia Eagles at RFK Stadium.

Trainer Bubba Tyer said Green's problem was caused Thursday by practicing on a rain-slickened artificial turf field at Redskin Park. The Redskins practiced on the artificial turf again yesterday because they wanted to avoid tearing up their wet grass field.

Alvoid Mays replaced Green in the workout "just as a precaution," defensive coordinator Larry Peccatiello said.

Green intially said he didn't want to discuss the matter, but when asked if he would be able to play Sunday without a problem he replied with a chuckle: "I hope so. I think I'll be out there." Another Break for Giants

The Redskins' public relations staff has compared the strength of the remaining schedules of the NFC East teams, and because of unexpectedly poor starts by some teams that did well last season and the luck of the draw, they discovered the division-leading New York Giants (5-0) have the easiest road. The Redskins (3-2) have the second-most difficult.

With the current records of the teams it has to play twice being counted twice, New York's remaining opponents have a combined 25-33 record. Phoenix's remaining opponents are 35-25, Washington's 32-28, Philadelphia's 31-29 and Dallas's 25-27.

The Giants play the Rams, who are 1-4, and the Vikings and Patriots, who are 1-5. Their only remaining opponents with winning records are Washington, San Francisco and Buffalo. But after playing the Cardinals and Redskins at home the next two weeks, six of New York's last nine games are on the road.

In addition to the Giants, the Redskins play Buffalo, which is 4-1, and Miami and Chicago, which are 5-1.

Phoenix's next four games are against the Giants, Bears, Dolphins and Bills. The Cardinals play the Giants again in the penultimate game of the season. And Furthermore . . .

Running back Ernest Byner, who threw a touchdown pass on an option play Sunday against the Giants, is the only player in the NFL this season to have touchdowns rushing, receiving and passing. . . . Quarterback Mark Rypien and his wife, Annette, attended Thursday night's White House dinner for Hungarian Prime Minister Jozsef Antall. Among the highlights of Rypien's evening was meeting actor Kevin Costner. "That was pretty cool," said Rypien, who reported that Costner "knows sports inside and out." . . . Linebacker Ravin Caldwell came out for practice with a towel bearing the initials "T.O." tucked in the waistband of his pants, presumably in honor of recently waived tight end Terry Orr.
