Figure skater Nancy Kerrigan returned home to find a magnetic resonance imaging of her right knee showed no damage to the kneecap and no injury to ligaments.
Kerrigan, attacked Thursday at U.S. Figure Skating Championships in Detroit, limped slightly at Logan International Airport.The skater could return to the ice within a week. She will begin physical therapy in a pool to strengthen the knee and improve range of motion, then work on a stationary bicycle.
The injury forced her to withdraw from the championships, where top two finishers normally represent U.S. at the Olympics. Tonya Harding won and Kerrigan was given a waiver for the other berth.
Kerrigan hopes to resume skating next Monday. The women's skating competition is scheduled the last weekend in February in Lillehammer, Norway.
In Detroit, investigators awaited enhancement of a videotape they said showed the assailant waiting for Kerrigan and fleeing after the attack.
