There's a featherweight slugfest in the works between up-and-coming 145-pound prospects Mackens Semerzier (5-1) and Anthony Morrison (15-8) currently being assembled for the upcoming WEC 48 pay-per-view from the Arco Arena in Sacramento, CA, on Saturday, April 24.

MMAmania.com learned of the pending match-up late Sunday night.

Semerzier made a huge impact in his promotion debut back at WEC 43: "Cerrone vs. Henderson" in October 2009 when he shocked the heavily-favored Waggney Fabiano by submitting the jiu-jitsu black belt with a sneaky triangle choke of his own.

Unfortunately "Mack da Menace" was unable to capitalize on his momentum, dropping a unanimous decision loss to the rugged Deividas Taurosevicius at WEC 46: "Varner vs. Henderson" earlier this year.

Like Semerzier, Morrison came up snake eyes at January's WEC 46 event when he was faced with the unenviable task of trying to stymie the onslaught of Mike Thomas Brown in the former featherweight champion's first match since coughing up the 145-pound crown to Jose Aldo last November.

A pretty tall order for anyone in the stacked featherweight division, let alone a promotion newcomer. Fortunately the WEC is giving "Cheesesteak" a second chance to prove he belongs but Semerzier is going to provide a fairly stiff test.

WEC 48: "Aldo vs. Faber" features a featherweight championship bout between the local fan favorite "The California Kid" Urijah Faber and unstoppable 145-pound champion Jose Aldo.

Also announced for the main card is a lightweight championship brouhaha between champion Ben "Smooth" Henderson and challenger Donald "Cowboy" Cerrone. Former featherweight champion Mike Brown will also take part in the event when he enters the cage opposite Manny Gamburyan.
