UTSA announced Tuesday that it will play Colorado State in a four-game series from 2015-18.

SAN ANTONIO — UTSA officials announced Tuesday a four-game series with Colorado State, which will be played in 2015-18, and that the program is moving its 2012 home game against Southern Utah from Sept. 15 to Oct. 20.

The Roadrunners will host the Rams on Oct. 3, 2015, and Sept. 29, 2018, at the Alamodome and travel to Fort Collins, Colo., for games on Oct. 1, 2016, and Sept. 30, 2017.

This marks the sixth contract to be signed with an NCAA Division I Football Bowl Subdivision (FBS) opponent.

UTSA announced earlier this month that it will play Houston on Sept. 21, 2013, at the Alamodome and again on Aug. 30, 2014, at Robertson Stadium in the Bayou City. That announcement came one day after unveiling a three-game series with Kansas State, which will take place on Sept. 27, 2014, and Sept. 15, 2018, in Manhattan, Kan., and on Sept. 12, 2015, at the Alamodome.

The Roadrunners announced in April a pair of contracts with schools from the Desert Southwest.

UTSA will face Arizona on Sept. 14, 2013, in Tucson, Ariz., on Sept. 6, 2014, at the Alamodome and on Sept. 5, 2015, again at Arizona Stadium. The Roadrunners also will play Arizona State on Sept. 17, 2016, in the Alamodome and on Sept. 1, 2018, in Tempe, Ariz.

The program unveiled in March a three-game series with Baylor that will be played on Sept. 9, 2017, at Floyd Casey Stadium in Waco, on Sept. 8, 2018, in San Antonio and on Sept. 7, 2019, back in Waco.

UTSA released its inaugural schedule that same month, which includes home games against Northeastern State (Sept. 3), McMurry (Sept. 10), Bacone College (Sept. 24), South Alabama (Oct. 8), Georgia State (Oct. 29) and Minot State (Nov. 19). UTSA has road dates at Southern Utah (Sept. 17), Sam Houston State (Oct. 1), UC Davis (Oct. 15), Northwestern State (Oct. 22) and McNeese State (Nov. 12).

Sam Houston State (Sept. 8), Southern Utah (Oct. 20), UC Davis (Oct. 27) and McNeese State (Nov. 10) all will return games at UTSA in 2012. UTSA will return games to South Alabama (Sept. 1) and Georgia State (Sept. 29) that same season.

All schedules are tentative and subject to change.

The University of Texas System Board of Regents unanimously approved UTSA’s Athletics Initiative Business Plan on Dec. 18, 2008, which granted the university permission to add a football program. On March 6, 2009, Coker was introduced as the program’s first-ever head coach.

UTSA will begin play as an NCAA Football Championship Subdivision (FCS) Independent in 2011. It then will notify the NCAA in June 2012 of its intent to advance to the Football Bowl Subdivision (FBS) by 2014. The Roadrunners will comply with FBS standards during the 2013 season, then will seek full FBS membership and bowl eligibility in 2014.

UTSA signed its first recruiting class in February and will redshirt all incoming players during the 2010-11 school year. The first practices will be held this fall and the first game will be against Northeastern (Okla.) State on Sept. 3, 2011, at the Alamodome.
