d'Arnaud still experiencing concussion symptoms

NEW YORK -- With Travis d'Arnaud's concussion symptoms lingering, the Mets catcher will remain out for the foreseeable future.

d'Arnaud has not played since Alfonso Soriano struck him in the helmet with a backswing on May 13. He would have been eligible to come off the seven-day concussion disabled list on Tuesday, but the Mets will not remove him from that list until he demonstrates marked improvement.

"He's still feeling the effects of the initial impact, so at this point, I don't have a real good prognosis on when he will be back," general manager Sandy Alderson said. "At this point, as he exercises, he still experiences some symptoms. As a result, we're still in the recovery period."

In order to return, Alderson said, d'Arnaud must pass a post-concussion test, but the Mets will not ask him to do so until he is asymptomatic. Because d'Arnaud is on a specialized head-injury list and not the regular 15-day disabled list, Major League Baseball and the Players' Association must approve his return.

"We don't feel he's in a situation today where he should take that test," Alderson said. "Until he's feeling better, we won't run him through that testing."

In the interim, Anthony Recker and Juan Centeno will continue to split time at catcher.
