Columbus Crew striker Emilio Renteria is out for the clash with New England Revolution and defender Chad Marshall is in doubt says coach Robert Warzycha.

Renteria was subbed at half-time of the Crew's CONCACAF Champions League 1-0 win over Santos Laguna on Wednesday with a groin injury whilst Marshall copped a kick in the head and is under a cloud.

"He didn't pull anything," Warzycha said of Renteria. "He just said something was not right."

As for Marshall: "Knowing Chad, probably he'll be fine, He needs some rest anyway. If he's not ready to play, he's not ready to play."
