Turner Sports, CBS’s partner in carrying the N.C.A.A. men’s basketball tournament, could carry the Final Four and national championship game in 2014, instead of 2016 as originally envisioned. The two are paying $10.8 billion to share coverage of the tournament from 2011 to ’24, with the games being broadcast on CBS, TBS, TNT and truTV.

CBS and TBS were to begin alternating the Final Four and championship game in 2016. But a CBS Sports spokeswoman said the 14-year contract includes a “provisional option” that would allow the rotation to start in 2014.

“There is no timetable for a decision,” she said.
