PORT ST. LUCIE, Fla. -- Matt den Dekker suffered a broken right wrist on Sunday's attempted catch.
He is expected to travel to New York on Monday, where he will be evaluated for the need for surgery.
"We don't know how serious it is," Sandy Alderson said. "It's serious enough, but we won't know any details about the exact condition or recovery time until the doctors take a look up in New York. But the initial films came back positive."
Said den Dekker: "It's disappointing, but you can't do anything about it. It's just a setback. I'm going to go to New York and figure out what I have to do next."
Den Dekker described the wrist as "a little painful right now."
He added: "This is the first time I had to deal with anything like this. I've never broken anything. It sucks, but I can't do anything about it."
