The Washington Redskins have re-signed Chris Keating once again to bolster their ailing linebacking corps, General Manager Bobby Beathard announced yesterday.

To make room for Keating, a 6-foot-2, 233-pound linebacker, the Redskins waived rookie running back Reggie Branch.

Following the Redskins' 13-7 loss to Dallas, three of their five linebackers -- Neal Olkewicz, Monte Coleman and Stuart Anderson -- had injuries.

Keating, a seventh-year player out of Maine, was first signed before the fourth game of the season, when Coleman went on injured reserve. He was released three weeks ago, then re-signed the next day when Coleman was not ready to return. The day before the Dallas game, Coleman was activated and Keating released again. He previously played for Buffalo between 1979 and 1984.

Of the ailing linebackers, Olkewicz appears to have the most serious injury. The middle linebacker tore his right pectoral muscle in the first quarter against Dallas but played the rest of the game.

"It looks better today than it did yesterday," said Redskins head trainer Bubba Tyer. "We're taking it on a day-to-day basis . . . By looking at him, I think he has a chance of playing."

If Olkewicz can't play, Rich Milot will move from right linebacker to inside linebacker and Coleman will play right linebacker.

Coleman strained the hamstring he had pulled earlier in the year. "It's not bad," Coleman said. "I knew after the game I didn't pull it."

Anderson has played with sore knees for a good part of the season. Only Milot and Mel Kaufman, the left linebacker, are healthy.

Tyer also reported that offensive tackle Joe Jacoby's right knee was less tender, but that he would be examined today or Thursday before a decision was made on whether he would play.
