Former WEC featherweight title contender Leonard Garcia has agreed to step in for Cub Swanson and will face Korean prospect Chang Sung Jung on the unaired preliminary portion of the WEC 48 card in April. News of the change was first reported by MMAWeekly.com.

It is not yet known why Swanson was forced off the event.

Garcia (13-5-1), winless in his last two bouts, most recently fought to a draw with George Roop at WEC 47 earlier this month. He previously suffered a unanimous decision loss to Manny Gamburyan at WEC 44 in November.

Garcia has put together a 3-2-1 WEC record since debuting with the promotion in February 2008, scoring wins over Hiroyuki Takaya, Jens Pulver and Jameel Massouh. His only other WEC loss was against former WEC featherweight champion Mike Brown.

Jung, who recently signed a six-fight contract with the WEC, hasn't fought since defeating Matt Jaggers at Sengoku 9 in August. He previously suffered his first career loss against Masanori Kanehara at Sengoku 8 last May.

Jung has also competed for Pancrese, Deep and Korea FC during his three-year career. He sports a nearly perfect 10-1 MMA record, scoring stoppages in eight of those wins including six by submission. Jung holds a notable career win over UFC veteran Michihiro Omigawa.

WEC 48: "Aldo vs. Faber" takes place on April 24 at the ARCO Arena in Sacramento, Calif., and the event's main card will be televised live on Pay-Per-View, which will be the promotion's PPV debut. The event is headlined by a WEC featherweight championship bout between champion Jose Aldo and challenger Urijah Faber.

In addition, WEC lightweight champion Benson Henderson will take on Donald Cerrone in a rematch from their previous "Fight of the Year" candidate at WEC 43 in October. Also, former WEC featherweight champion Mike Brown will look to get back on the winning track against the streaking Manny Gamburyan.
