Running back Herschel Walker will miss the Dallas Cowboys' first three preseason games because of a sore right knee. The problem, first thought to be a bruise, has been re-diagnosed as a sprained ligament.

Seven Dallas receivers were hurt last week. Four will miss extensive playing time.

New England Patriots:

Quarterback Tony Eason ended a nine-day holdout by signing a one-year, $875,000 contract. He and his agent had wanted to approximate the earnings of million-dollar-per-year quarterbacks Jim Kelly, Dan Marino, Vinny Testaverde, Joe Montana, John Elway, Bernie Kosar and Warren Moon.

Minnesota Vikings:

Pro Bowl strong safety Joey Browner ended his holdout, second-round draft choice Ray Berry, a linebacker, agreed to terms and cornerback Issiac Holt practiced after completing treatment for alcohol problems.

For the rest of this week, Holt, a third-year pro who led the team with eight interceptions last season, will miss the morning workouts and about half of the afternoon practices because he must perform eight hours of community service daily. After this week, Holt will perform eight hours of community service for each of the next 25 weeks as part of his sentence for aggravated driving while intoxicated.

Indianapolis Colts:

Cornerback Chuck Miller, an eighth-round draft pick from UCLA, broke his leg and will be out indefinitely. Also, eighth-year veteran Eason Ramson retired.

St. Louis Cardinals:

Defensive end David Galloway suffered a broken left forearm Monday night and will be sidelined an indefinite period. Galloway, a six-year veteran, was projected as a starter.

Detroit Lions:

Backup quarterback Joe Ferguson signed for the season. He will earn about $400,000.
