THE SIDELINES : Lansford’s Injuries Reviewed

Doctors today were still reviewing medical tests on Oakland Athletics third baseman Carney Lansford after he injured his left knee and right shoulder in a New Year’s Eve snowmobile accident.

Lansford suffered no broken bones, was never a hospital inpatient and is walking, but the A’s said they still did not know if the injury would cause Lansford to miss part or all of the 1991 season.

“He could be out an hour or out for the season,” team doctor Allan Pont said. “We just don’t know yet.”

Lansford, 33, was hurt while riding his snowmobile near his ranch in Baker, Ore., Alves said. The team did not know the circumstances of the accident.

He underwent magnetic resonance imaging tests on his shoulder and knee at Children’s Hospital in San Francisco on Thursday, shortly after he arrived from Oregon.

The test “suggested there was not serious cartilage damage (to Lansford’s knee). There remains the possibility of ligament problems,” Pont said late Thursday night.

Lansford suffered “only moderate right shoulder problems,” said Pont, who did not believe that there was any rotator cuff damage.
