The Pittsburgh Steelers were expected to notify the National Football League today that quarterback Terry Bradshaw will be placed on the physically unable to perform list because of an elbow problem.

Bradshaw arrived at the Steelers' training camp in Latrobe, Pa., with a sore throwing arm stemming from surgery last winter in which a muscle in his right elbow was cut and reattached. He said an off-balance throw during the team's minicamp in May "set my rehabilitation back a month."

Coach Chuck Noll said listing him as unable to perform would allow Bradshaw to "run and throw and rehabilitate himself." He would be unable to practice in pads or join in any contact practices while on the list.

Meanwhile, Steeler running back Russell Davis, the onetime Woodbridge, Va., high school star, says he has the rare blood disorder that once caused former Steeler defensive back J.T. Thomas to miss an entire season. Davis plans to play this season, but is "saying my prayers regularly. I just have to see if I can maintain conditioning."

Doctors still don't know how to treat Davis' disease, a form of Boeck's sarcoidosis.

The 231-pound Davis said he was hospitalized a week in March. He said he had experienced "extreme discomfort," but he isn't in pain now, though steroid treatments have given him a slightly bloated appearance and "sometimes I get dizzy running" . . .

Redskins General Manager Bobby Beathard said draftees Bob Winckler, Wisconsin offensive guard, and Richard Williams, Memphis State running back, have agreed to contracts.

Auto Racing: Al Holbert and Jim Trueman gained a $10,000 victory in the $50,000 Pepsi GT Grand Prix at Brainerd (Minn.) International Raceway, covering 500 kilometers (312 miles) in 3 hours 10 minutes 64 seconds, and Kathy Rude, 26, was badly injured in one of two crashes involving female entrants.

Rude, of Seattle, was hospitalized in serious condition with multiple fractures and internal injuries. Her Porsche running at racing speed hit the rear of a slow-moving vehicle heading for a pit.

Rude's car leapfrogged the BMW driven by Diego Montoya and traveled about 150 yards on down the track. Workers spent several minutes cutting through the wreckage to bring her out. She remained conscious. Montoya incurred burns on his torso when he leaped from his car shortly before impact. His BMW exploded into a fireball and Montoya fell unconscious but was carried to safety. He had been heading for a pit with a broken transmission.

Earlier, Desire Wilson lost control due to a broken suspension bar and cartwheeled her March GTP several times. The vehicle came to rest upside down; she escaped shaken up and with a broken left ankle . . .
