DENVER -- Potentially weeks away from his Major League debut, Mets top prospect Travis d'Arnaud fractured a bone in his left foot Wednesday while playing for Triple-A Las Vegas. d'Arnaud is scheduled to fly to New York for reexamination Friday at the Hospital for Special Surgery.

d'Arnaud took a foul ball off his foot while catching at Vegas, sustaining a non-displaced fracture of the first metatarsal bone. He is currently in a walking boot, and general manager Sandy Alderson said he is unsure if d'Arnaud will require surgery.

"I feel terrible for Travis," manager Terry Collins said. "I feel terrible for us."

The centerpiece of last winter's seven-player blockbuster that sent R.A. Dickey to the Blue Jays, d'Arnaud was hitting .250 with five doubles, one home run and a .901 OPS in 12 games for Las Vegas. The general sense within the organization was that the Mets were prepared to promote him to the Majors around midsummer.

That timetable now hinges upon the health of d'Arnaud's foot.

"It's part of the game," Collins said. "He's a catcher. Stuff happens."

Ranked the No. 6 prospect in baseball on MLB.com's 2013 Prospect Watch, d'Arnaud was on the cusp of the big leagues last summer with the Blue Jays before tearing a ligament in his left knee while sliding into second base, ending his season. He returned to game action this spring in Major League camp with the Mets.

Collins on Thursday echoed Alderson's comments from earlier this season, that d'Arnaud had been first in line for a promotion in the event that starting catcher John Buck suffered an injury. Buck has instead quieted early-season calls for d'Arnaud's promotion by hitting .326 with six home runs and a National League-leading 19 RBIs.

Still, the organization is suddenly thinner at catcher, with Buck and Anthony Recker on the big league roster, and Landon Powell the primary backup at Las Vegas.

"What happens if John Buck breaks his foot today?" Collins said. "What we had in place if something should happen now has to change."
