Detroit Manager Sparky Anderson may be listening on the radio in a hospital room today when the World Series-champion Tigers open the American League season against East Division rival Cleveland.

Anderson has an inflammation in the blood vessels and nerves of his knee, with swelling of his entire left leg, according to Tigers team physician Clarence Livingood.

Special X-rays showed no sign of a blood clot, Livingood said, but other tests to determine origin of the inflammation are in progress.

Anderson's participation in Detroit's opening day ceremonies, during which the members of the 1984 World Champions are to receive their rings, was to be determined later, Livingood said.

Anderson was hospitalized late Saturday after an increasingly painful and swollen leg immobilized him.

He twisted his leg Thursday while running from the dugout to the third base coaches' box in Dunedin, Fla., during an exhibition game against Toronto.

If Anderson cannot be on the bench, coach Dick Tracewski likely will manage the team.

Jack Morris, 19-11 during the regular season before winning one American League championship series and two World Series games in 1984, is expected to start for Detroit against the Indians' Bert Blyleven, 19-7 a year ago.
