Two-time world champion Juan Manuel Lopez (31-2, 28KOs), who is serving a 10-month suspension for his remarks against the referee Roberto Ramirez after suffering a technical knockout loss, for the second, to WBO featherweight champion Orlando Salido of Mexico, will undergo another series of medical examinations following his own admission that he suffered spells where he "blacked out" during three of his fights, including both of the bouts with Salido.

The need for additional tests were announced by the president of the Professional Boxing Commission, Dommys Delgado, who said there was a medical recommendation to turn up the statutory medical suspension from two to six months.

Lopez's suspension, for calling referee Ramirez "a gambler," will expire in March 2013 - but in order to obtain his license he must comply with the recommendations of the medical commission.
