Wide receiver Calvin Muhammad will miss the next one to two weeks of practice after suffering a compound dislocation of the left middle finger Wednesday night, Washington Redskins head trainer Bubba Tyer said today.

"His bone was sticking out of his skin, which is the definition of a compound injury," Tyer said. "There was no tendon damage and he has full function of his finger. We just sewed him up."

The injury occurred on the next-to-last play of the team's midweek scrimmage. Muhammad was reaching for a pass in the end zone when cornerback Vernon Dean hit Muhammad's hand, knocking it against the ball.

It is the team's sixth finger injury of the summer.

"We've had bad luck with that," said Coach Joe Gibbs.

Muhammad has been sharing time on the first team with Charlie Brown and Art Monk. The coaches have been pleased with his performance.

Brown, meanwhile, has just returned to practice after straining a right hamstring July 29.

Now, the Redskins will be without Muhammad for the preseason opener Saturday with the Atlanta Falcons. He hopes to return by a week from Sunday to play the Raiders in Los Angeles.

"He can run, but he can't catch anything for a while," Tyer said.

Wide receiver Mark McGrath is not expected to play against the Falcons because of a strained left thigh, Tyer said . . . Linebacker Larry Kubin suffered a bruised left thigh during the scrimmage, Tyer said. It is not believed to be serious . . . Tackle Mike McClearn, who ruptured a tendon in his left middle finger July 22, practiced without a protective pad on his hand and aggravated the injury. "It's swollen and sore, but I think he'll be able to practice -- with a big pad this time," Tyer said.

Mark Moseley-Tony Zendejas update: With Moseley again sitting out because of a sore right thigh, Zendejas made 14 of 18 field-goal attempts, including two of two 53-yarders and one of three 57-yarders.

"And those two misses (from 57 yards) were both long enough, just slightly to the left," said special teams coach Wayne Sevier.

The Redskins still plan to use Moseley Saturday, Sevier said, but the final decision may not be made until pregame warmups.

Newly acquired running back Michael Morton has been impressive. Morton, a 5-foot-8, 180-pound, three-year veteran from Tampa Bay, will be worked into the Redskins' system "as fast as we can," Gibbs said.

"He looked good tonight -- quick," Gibbs said after the scrimmage.

In his career, Morton has returned 89 kickoffs for 1,885 yards and has gained 58 yards in 31 carries. -- Christine Brennan
