The Arizona Cardinals beefed up their offensive line a bit Wednesday by signing veteran free agent guard Chilo Rachal to a contract.

Terms of the deal were not disclosed by the team.

Rachal, 27, spent last season with the Chicago Bears where he started eight games at left guard.

Prior to his season in Chicago, Rachal spent four years with the San Francisco 49ers, who selected him in the second round of the 2008 NFL Draft out of USC. In his four years with the 49ers, Rachal started 38 games at right guard.
