Despite rumors and speculation, Monaco's co-stars Steve Burton (Jason Morgan) and Nancy Lee Grahn (Alexis Davis) have denied she is departing from the show.

Oliver "The Atomic Bull" McCall (born April 21, 1965) is an American professional Heavyweight boxer best known for winning the WBC Heavyweight Championship in 1994 after scoring an upset knock out victory over Lennox Lewis, in Lewis' home town of London, England, followed by his infamous in-ring meltdown in the rematch. In a long rollercoaster career that has been blighted by drug addiction and almost constant legal troubles, McCall has served as the chief sparring partner for a peak Mike Tyson, then later come into his own as a professional, defeating Lewis, Larry Holmes, Lionel Butler, Bruce Seldon, Jesse Ferguson, Francesco Damiani, Oleg Maskaev, Henry Akinwande, Przemyslaw Saleta, Sinan Samil Sam, and Fres Oquendo.

McCall had a strong amateur career prior to turning pro, twice a winner of the Chicago Golden Gloves.

McCall turned pro in 1985 and slowly worked his way up the heavyweight ranks. He beat Jesse Ferguson and future heavyweight champion Bruce Seldon and lost a very close decision to Tony Tucker before landing the shot against Lewis in 1994. After a close first round, McCall came out aggressive in the second and landed his signature counter right hand as Lewis moved forward. Lewis dropped to the canvas and got up before the count of ten, but he was unsteady on his feet, and the referee waved a stop to the fight.
