HARLINGEN – It’s a sport with a lot of action, a lot of elbows flying and a lot of hard hits.

Roller derby is a sport gaining momentum in the Rio Grande Valley.

The game consists of five members on each team, one jammer and four blockers.

The blockers try to clean a path for their teammate, the jammer, while stopping the opponent’s jammer.

Trust us when we say those hits can really hurt.
