When the Big 12 announced it was adding West Virginia, the league said the Mountaineers would join on July 1, 2012.
But the Big East said in its statement that West Virginia would be held to conference bylaws, which stipulate a 27-month waiting period.
On a conference call Friday afternoon, school president James Clements said he was confident the Mountaineers would be full members of their new league in 2012. He said negotiations were underway with the Big East to get that done, but declined further comment.
"Our intent is clearly July 1 we will be a member of the Big 12," Clements said. "Our team and their team are in discussions about how to make that happen."
The Big East also has said it would hold departing members Pitt and Syracuse to the 27-month waiting period.
