Ultimate Fighter veteran Jamie Yager, Greg Parker, Ozzie Alvarez and Andrew Ramm have all been added to the upcoming World Series of Fighting 28 event, officials announced recently.

Set for February 20 from the Next Level Sports Complex in California, the main card will air live on NBC Sports Network. The event is highlighted by a bantamweight title fight pitting champion Marlon Moraes against Joseph Barajas.

The other main card bout will be Timur Valiev vs. Chris Gutierrez in a meeting of bantamweight contenders.

Below is the fight breakdown concerning Yager-Parker and Alvarez-Ramm:

Jamie Yager vs. Greg Parker

The 32-year-old Yager of Huntington Beach, Calif. will return to the cage after being sidelined for three years due to injuries.

A lifelong athlete who took up Jiu-Jitsu while attending Pasadena City College, Yager was the middleweight winner of the 2008 MMA competition reality television series, The Iron Ring, that aired on BET.

Yager went on to compete in season 11 of The Ultimate Fighter reality series, scoring a punishing, 26 second KO on Ben Stark with a head kick in the first episode and, later, a first round (1:09) TKO (strikes) on Charles Blanchard.

In his last effort, the 31-year-old Parker of Irvine, Calif. rebounded from his first career defeat, submitting Daniel McWilliams with a rear-naked choke in the first round (2:22) of their meeting on October 2, 2015.

Between March 2009 and April 2011, Parker was perfect as an amateur, compiling a 3-0 record, before running to four consecutive wins, all by way of (T)KO or submission, in his first four professional bouts.

Ozzie Alvarez vs. Andrew Ramm

Originally from Miami, Fla., the 30-year-old Alvarez fights out of Huntington Beach, Calif. and has gained recognition as a dangerous power puncher since he turned professional in 2010.

In what will be his first start of 2016, Alvarez will look to bounce back from a unanimous decision defeat at the hands of Justin Patterson on September 17, a result that snapped a five-fight win streak.

Alvarez’s five consecutive victories all came by way of (T)KO or submission, and all but one of them occurred inside the first round of action.

Ramm of Costa Mesa, Calif. via Bremerton, Wash. is a 31-year-old submission expert who recently earned his black belt in Brazilian Jiu-Jitsu under mentor and famed trainer Eddie Bravo.

To date, Ramm has produced all of his professional career victories by way of submission and, in a span of just 11 months between 2012 and 2013, he amassed a perfect 6-0 record under amateur status.
