Tickets also were sold through the Redskins' ticket office and through online specials at discount sites like Living Social.
About 30,000 total tickets have been sold, well below the stadium's capacity of about 85,000.
Wells expected the majority of those who show up Saturday will be wearing gold and blue.
"I expect that we'll have a little bit more than 20,000 Mountaineer fans at the game," he said.
But even though the field is inside the Washington, D.C., beltway, some of the state's most prominent Mountaineer fans likely will not be present.
Sen. Jay Rockefeller, D-W.Va., will be in Wheeling on Saturday hosting a roundtable event to discuss prescription drug abuse and its effect on high school students. He'll speak at the Ohio County Jefferson-Jackson Dinner that night.
Sen. Joe Manchin, D-W.Va., likely will miss the game.
Manchin spokeswoman Emily Bittner said he would like to attend to help honor his friend and former Mountaineer Sam Huff, who will be recognized by Clements and Luck after the first quarter.
But Bittner said the Senate is scheduled to hold several key votes on a jobs package for veterans throughout the day Saturday. The votes are currently scheduled for 7:30 a.m. and 2:30 p.m.
"The senator is hoping to be at all of those," Bittner said. "His priority is to vote for the Veterans Job Corps Act, particularly for the vote on its final passage."
Bittner said if the schedule changes, Manchin may try to go to Fairmont to attend the funeral or wake for Ron Radcliff, a longtime friend who served as Workforce West Virginia director when Manchin was governor.
The viewing is scheduled for Friday and the funeral at 11 a.m. Saturday.
