New York, NY -- (Sports Network) - A second opinion on the injured knee of New York Mets center fielder Carlos Beltran remains a bone bruise.

The Mets confirmed on Tuesday that Beltran visited noted surgeon Dr. Richard Steadman in Colorado on Monday and the doctor agrees with the initial diagnosis by the Mets.

There was speculation that the injury could have been more serious, possibly a microfracture that would have required surgery.

The Mets had initially indicated that Beltran would be sidelined through the All-Star break, but the timetable for his return could be longer. Surgery could have potentially ended his season.

Beltran has been dealing with a balky right knee since mid-May, and an MRI exam performed on June 22 showed that the bone bruise had worsened over time. He was placed on the 15-day disabled list later that day.

The switch-hitting Beltran has a .336 average this season with eight homers and 40 runs batted in through 62 games. The 32-year-old has 11 stolen bases and a .425 on-base percentage.
