The Lakers, Hornets and Rockets are expected to appeal the NBA's decision to block their agreed upon three-way trade involving Chris Paul, according to sources.

The main argument is that Paul would not be able to be traded to anybody if the NBA blocks this trade.

On Thursday, the Lakers agreed to acquire Paul in exchange for Pau Gasol and Lamar Odom. Houston would acquire for Gasol while sending Kevin Martin, Luis Scola, Goran Dragic and a first round pick. The Hornets would receive Odom, along with Martin, Scola, Dragic and the first round pick.
