BoxingScene.com has been advised that a potential fight between Amir Khan (27-3, 19KOs) and Josesito Lopez (30-5, 18KOs) is a "no-go" due to weight. Khan has a set date on Showtime for April 20th. He would like to stage that match in the UK, where he has not fought since April 2011.

Lopez, who last fought at junior middleweight for his match with Saul Alvarez last September, was open to the idea of meeting Khan at a catch-weight of 145 - and Khan was looking for something much closer to the junior welterweight limit of 140.

Khan recently faced a similar issue with former WBA welterweight champion Vyacheslav Senchenko (33-1, 22KOs). As with Lopez, Khan wanted to face Senchenko at a catch-weight close to the junior welterweight limit. Senchenko was unwilling to go below 146.

Another possibility, for Khan, is Humberto Soto. The Mexican veteran returned to the ring on Saturday in Mexico to decision Silverio Ortiz (26-14) but he wasn't exactly impressive in doing so.

For Lopez, there have been discussions about matching him against Marcos Maidana (33-3, 30KOs) in a welterweight fight. Sources close to the negotiations have told BoxingScene that "both sides" are very interested in the fight. Maidana-Lopez would be a very physical match, with high drama, and because of their styles I wouldn't expect it to go the distance.
