The Rio Valley Grande Sol were a professional indoor football team based in Hidalgo, Texas. They were members of the X-League Indoor Football (XLIF) in their final season. The Sol played their home games at the State Farm Arena. They were founded in 2014 as members of the Lone Star Football League but withdrew their team from the league after being taken out of the championship game unfairly after their inaugural regular season.
The Sol were the third indoor football team to call Hidalgo home, following the Rio Grande Valley Dorados which played in af2 from 2004 to 2009. The second was the Rio Grande Valley Magic, which played in the Southern Indoor Football League in 2011 and in the Lone Star Football League from 2012 until their franchise charter was revoked in 2013.
