The Bullets made their second roster change in three days yesterday when they signed rookie free agent Keith McCord to a 10-day contract.

McCord, a 6-foot-7 forward from Alabama-Birmingham, was one of the last players cut by the Philadelphia 76ers this preseason.

He takes Carlos Terry's place on the Bullet roster.

Terry had surgery Tuesday to repair a torn cruciate ligament in his left knee and probably will miss the rest of the season.

Bob Dandridge was put on the injured list Monday and David Britton was signed to a 10-day contract to take his place.

"We're still looking," Coach Gene Shue said. "We have a long list of available people, but there just aren't any veterans out there that we know can help. We've thought about bringing in people like Ray Townsend, Tate Armstrong, Willie Smith and Nate Williams, and we're still thinking about it.

"We're going (with younger players) right now because maybe one of these guys will develop. We do need help right away, but it just isn't there. We have to look at all the possibilities, and that means trades and everything.

"Right now, we're just looking for players who might have some potential."

General Manager Bob Ferry has been high on McCord for a long time.

"He's a real physically talented player," Ferry said. "He's fluid and very clever inside. I've been impressed with him from the first time I saw him when he was in college and I even tried to get him from Philadelphia before the draft."

McCord played three years at Alabama, then transferred to Alabama-Birmingham and played for Gene Bartow. Because he was a transfer, he had to sit out the 1978-79 season, which made him eligible for the 1979 draft.

The 76ers drafted him as a future, but he stayed in school, which meant he remained the property of the 76ers until the 1980 draft. Instead of reentering the draft pool, he signed with the 76ers.

After being released, he played one game for the Philadelphia Kings of the Continental League. He has been working out on his own the last few weeks.

"They (the Bullets) just signed me to a 10-day contract, so I have to show them what I can do," McCord said after yesterday's workout at Bowie State. "There's no guarantee."

Elvin Hayes and Wes Unseld have sore knees and neither worked out yesterday. But Austin Carr did, after being sidelined the last three weeks following minor knee surgery. He ran and shot well and said he felt well. It is not known if he will play Friday against the New York Knicks at Capital Centre.

Shue said he is planning to use Kevin Grevey as the backup small forward to Greg Ballard for the time being.

Grevey was still smarting yesterday from his incident with official Hugh Evans in Tuesday night's 96-94 loss to the Chicago Bulls.

Grevey was called for charging Reggie Theus and became so incensed he pounded the ball off the floor twice and charged Evans, cursing him. He shoved and bumped Evans before teammate Mitch Kupchak pulled him away.

Grevey was assessed two technical fouls and ejected from the game. Ejection means an automatic $225 fine, but he could be in more serious trouble. Evans reported the incident and the league has asked the Bullets for films of the game. Grevey could be subject to another fine and/or suspension.

"I just lost control for a bit there," Grevey said. "I was frustrated and mad."
