Philadelphia Union have declined contract options for Gabriel Gomez, Porfirio Lopez and Krystian Witkowski, the club announced today.

All three will be available in today’s Major League Soccer Waiver Draft at 3:30 p.m. Additionally, the release of Gomez and Lopez will free two international roster spots.

Gomez, 28, was acquired on December 21, 2011 from Mexican Second Division side Indios de Cuidad Juarez. The Panamanian international made 18 starts in 24 games and scored six goals.

Lopez, a 27-year-old defender, made four straight starts to start the season for a total of 327 minutes of action. The Costa Rican was acquired from Chinese side Dalian Haichang on Dec. 22, 2011.

Witkowski, 22, was drafted by the Union 26th overall in the MLS supplemental draft out of Marist College. He suffered a season ending concussion in March and did not see action in any first team matches.
