Bullet forward Mitch Kupchak will be activated in time for Sunday's game against Golden State if his ailing Achilles' tendon does not act up during a workout today.

"Mitch looked better practicing today (Friday)," said General Manager Bob Ferry, "and he said if it doesn't hurt or get worse, he'd like to play Sunday."

Kupchak would take Roger Phegley's spot on the roster. Phegley, who left practice Thursday after becoming ill and did not suit up for the Houston game that night, will be sidelined from 10 days to two weeks with acute gastroenteritis, which causes severe stomach pains. Redskin quarterback Billy Kilmer had the same illness before a playoff game against Minnesota, and spent several days in the hospital.

If Kupchak does return, Phegley will be placed on the injured-reserve list and would have to miss a minimum of five games before he can be reinstated.

According to a Bullet spokesman, Phegley vomited blood and has a laceration in the lower part of his esophagus that could become more severe with further physical activity. Phegley was examined by team doctor Herbert Singer.

Guard Kevin Grevey reinjured his chronic hamstring pull against Houston and did not play in last night's game against Seattle. He is listed as doubtful for Sunday's game against Golden State. Grevey has been hampered since Jan. 19 by the ailment and sat out three games last week while resting it. He scored 20 points against the Rockets.

Kupchak has played in only one game since Jan. 30. He was on the injured-reserve list until last night. The tendon has been bothering him since mid-January and he since has been placed in a cast and fitted with a leg brace in attempts to cure the inflammation.
