WASHINGTON (AP) - Nationals star Bryce Harper will see a specialist next week because the swelling in his knee hasn't improved.

Washington Nationals manager Davey Johnson said Thursday that Harper will visit Dr. James Andrews on Monday for a second opinion on the young slugger's left knee. Harper hasn't felt quite right since running into the wall at Dodger Stadium on May 13.

Harper has been diagnosed with bursitis in the knee, but none of his treatments has been successful in easing the swelling and inflammation. Johnson said the knee was swollen Thursday after Harper did some light jogging in a pool.

Harper is eligible to come off the 15-day disabled list on Tuesday, but he is likely to need more time to heal.
