Here We Go Again: According To TMZ, "NCAA Is Taking An Aggressive Look At University Of Kentucky Basketball Players".

Kentucky Basketball Players Subject of NCAA Probe

TMZ has learned the NCAA is taking an aggressive look at University of Kentucky basketball players -- past and current -- and their possible involvement with professional agents.

According to a source who was interviewed by an NCAA investigator, the agency is interested in at least four players -- two current and two who were just drafted by NBA teams.

In the case of one former Wildcat, we're told the NCAA wants to know about his relationship with his current agent. We're told the investigator asked about multiple meetings the agent allegedly had with the player ... dating back to the player's senior year in high school.

The insinuation is the agent had an arrangement with the player before he went to Kentucky.

It is a violation of NCAA rules for a student athlete to receive anything of value from an agent -- or to have any agreements, verbally or in writing, with an agent. Just ask USC, Reggie Bush or OJ Mayo.

Kentucky "declined comment" -- and a rep for the NCAA tells us, "The NCAA does not comment on current, pending or potential investigations.
