From MLB.com’s Marty Noble :

The Mets received word late Saturday that X-rays on Carlos Beltran were negative, hours after their center fielder had injured his left knee crashing into a chain-link fence in left-center field at Minute Maid Park.

Beltran, the team’s primary candidate for the Most Valuable Player award, was taken to a local hospital for additional examination, and he was diagnosed with a bruised left knee and he’s listed as day-to-day. Before leaving for the hospital, he limped conspicuously as he left the clubhouse after saying he couldn’t bear weight on his left leg.

At the time, the club wasn’t particularly concerned about his condition after a doctor, Warren Kadrmas (CQ), who had worked with the team in Spring Training, examined Beltran and said he found no significant damage.

“We think he just has a bad bruise,” manager Willie Randolph had said.

And Beltran, who said he felt little pain, said the swelling above the knee made it impossible to bend or straighten the leg normally. He kidded with teammates and reporters before his departure, comparing the immediate aftermath of his crash into the fence to his sickening collision with Mike Cameron last summer.

“Then I didn’t know I was,” he said. “This time I knew where I was. When I heard the booing, I knew I was in Houston.”
