Beltran, who has had pain in his right knee for much of the spring, went to Vail, Colo., to visit specialist Dr. Richard Steadman on Monday.
Steadman examined Beltran's knee and agreed with the Mets' medical staff that the injury is a bone bruise, a source told the Daily News. Steadman, whose specialty is microfracture surgery, likely will advocate Beltran rest through the All-Star break, the newspaper reported.
Steadman and Mets team doctor David Altchek have not had a chance to speak Tuesday morning, the Daily News reported.
Beltran received a cortisone shot on May 26, but the pain returned. A second MRI exam showed the bone bruise had expanded, which sent him to the 15-day disabled list on June 22. Beltran then requested a second opinion.
"With a player of this importance to us, there's no argument on our end to get another look," Ricco said Monday. "He asked to go have a second opinion, which is his right under the rules. With him, there's no reason for us to not be in favor of that. Our doctors are fully on board with that."
Beltran, a Gold Glove center fielder, was hitting .336 with eight homers, 20 doubles, 40 RBIs and 11 stolen bases.
He has had surgery on both knees before, in October 2007, when he was suffering from tendinitis. That procedure was to clear frayed tissue from the tendons.
