CHARLESTON, W.Va. -- The geographic footprint of Conference USA appears to be changing again.
According to CBS Sports College Football Insider Brett McMurphy, the league is prepared to add six schools for the 2013 season.
Extending invitations to the schools - Florida International, Louisiana Tech, North Texas, Texas-San Antonio, Charlotte and Old Dominion - is necessary after the league lost one-third of its members to the Big East and the previously announced "football association" with the Mountain West hit numerous legal snags.
Once the new schools officially join Conference USA - an announcement that could come as early as Friday, according to McMurphy - the league will have 14 schools, including Marshall.
Houston, Southern Methodist, UCF and Memphis are headed to the Big East after the 2012-13 academic year.
In an effort to keep pace with conference realignment and the burgeoning BCS leagues, C-USA and Mountain West announced its football association in October.
There was a formal announcement and conference calls and Marshall Athletic Director Mike Hamrick called it "an exciting development for Marshall athletics."
McMurphy's report said C-USA and the Mountain West "continue to work together on a plan to share scheduling, television and marketing resources."
Conference USA is tapping into five different leagues for expansion.
FIU, a team the Herd defeated in the Beef 'O' Brady's Bowl in December, is leaving the Sun Belt to join C-USA. North Texas is also coming from that league.
The WAC is losing Louisiana Tech and UTSA, although the latter hasn't played in the league yet.
