Mets' Josh Thole (concussion) to DL

PHILADELPHIA -- New York Mets catcher Josh Thole landed on the seven-day disabled list Tuesday with a concussion, a day after receiving a blow to the head from the Philadelphia Phillies' Ty Wigginton on a play at the home plate.

Manager Terry Collins said Thole still was experiencing headaches Tuesday.

Thole also suffered a concussion when he was struck with a backswing two years ago while catching for Triple-A Buffalo.

The Mets promoted former Seattle Mariners and San Diego Padres catcher Rob Johnson from Buffalo to share catching duties with Mike Nickeas. Right-hander Pedro Beato (shoulder) was transferred to the 60-day DL to clear a 40-man roster spot for Johnson.

Neither Collins nor Nickeas said he found anything dirty about the hard-nosed Wigginton's collision with Thole. Wigginton's left shoulder struck Thole in the right side of the face and knocked the catcher from the game.

"That's your buddy and your teammate," Nickeas said. "You get hit like that, it's never a good thing. But it is part of the game. I think he was just trying to kind of dislodge the ball and go in there hard. Wigginton was just playing hard and unfortunately caught Josh in a vulnerable spot.

"We've all been crushed," Nickeas continued. "I haven't ever been hit in the face, in the head, that it's jarred me like it looks like it got Josh. You get good ones. You get guys coming into you hard. Hopefully it just hits you in the right spot and you're able to absorb the impact. Josh kind of got clocked."

The seven-day DL for concussions was added last year. Brian Roberts, Al Alburquerque, Denard Span, Matt Treanor, Ronny Cedeno, Craig Gentry, Erick Almonte and Eli Whiteside all used it in 2011. Eric Chavez is the only other active player on the list.

General manager Sandy Alderson said shortstop Ruben Tejada also was evaluated Tuesday in New York for a concussion but was cleared. Tejada landed on the disabled list Monday with a right quadriceps strain.

Tejada went tumbling face first into the infield dirt Sunday at Citi Field after suffering the leg injury on an infield single.
