d'Arnaud to begin rehab assignment Sunday

NEW YORK -- In one of the last steps before returning from a concussion, Travis d'Arnaud will begin a rehab assignment on Sunday with Double-A Binghamton. He is expected to start behind the plate for the team's 6:35 p.m. ET game against New Britain.

On Saturday, d'Arnaud ran and took batting practice outside. Manager Terry Collins expected him to run the bases as well.

"This is the final stages of what he's got to do," Collins said. "I know he's going to be fine. He felt great yesterday with everything he did."

Collins suggested previously that d'Arnaud's rehab assignment could be as short as eight to 10 at-bats.

d'Arnaud has been out since May 13, when Alfonso Soriano's backswing caught him in the back of the head.
