A memo was issued on Tuesday by the NBA to remind teams about tampering rules, specifically about Chris Paul.

ESPN.com learned that the memo spells out that "no team should be having communications with Chris Paul or his agent or representative about a potential trade for Paul that have not been authorized in advance by the New Orleans Hornets."

Paul's agent Leon Rose has reportedly been in contract with several teams.

The memo, sources said, also threatens penalties for any such communications that could potentially include "suspension of the offending person, prohibition of the offending team from hiring the person being tampered with, forfeiture of draft picks and individual and/or team fines of up to $5 million."
