Cuttino Mobley has failed the physical administered after he and Tim Thomas were traded to New York in exchange for Zach Randolph and Mardy Collins.

The delay was earlier described as a "paperwork" matter but it was revealed that the Knicks were investigating concerns about the condition of Mobley's heart.  

Mobley will meet with another doctor on Tuesday.  

The Knicks are not expected to void the deal.  A team may waive the requirement that a player pass his physical to complete a trade.

Zach Randolph and Mardy Collins were forced to sit out Monday's game waiting for the trade to become final.
