Gennady Golovkin isn't the only boxer trying to monopolize an entire division and win all of the world titles. Terence Crawford wants to do the same in the junior welterweight division.

Crawford, the WBC and WBO world champion at 140 pounds, wrote on social media that he will move up to the welterweight division once he wins the WBA and IBF world titles.

Currently, the two world titles that Crawford does not hold are being held by Ricky Burns, the WBA champion, and Eduard Troyanovsky, the IBF champion. Troyanovsky defended his belt, along with the IBO title, against Keita Obara in September when Troyanovsky won via second-round TKO.

Burns and Crawford have already fought back in 2014 for a lightweight world title, with Crawford winning the belt. This was during Burns' fall from world title contendership from September 2013 to May 2015, when he did not win any of his three title fights and won just one bout during that five-fight stretch. Burns eventually won the then-vacant WBA title in May when he defeated Michele di Rocco via TKO.

Crawford had been fighting at 140 pounds since last year when he defeated Thomas Dulorme for the WBO title. The undefeated Crawford won the WBC title from Viktor Postol in his last fight in July. Crawford also became The Ring and lineal junior welterweight champion after beating Postol. Crawford is defending all of his four titles against John Molina on December 10 in an HBO-televised card from Omaha, Nebraska.
