Less than 48 hours after Chivas USA coach Chelis said he wouldn’t be adding more players to the roster in the run-up to Saturday’s MLS opener — he added a pair of players to the squad.

Both are known quantities who have played for Chelis before: center back Joaquin Velazquez, 37, and Peruvian international left back Walter Vilchez, 31, played for Puebla when Jose Luis Sanchez Sola guided the club to the top tier of Mexican soccer in 2007.

Vilchez has 64 caps, is a five-time champion in Peru and made his pro debut in 2000 for Deportivo Wanka, while also appearing for Cruz Azul.

Chivas USA opens MLS play against Columbus Saturday in Carson; it’s unclear whether the pair will receive the necessary paperwork in time to allow them to play in the game.
