First domino down? Colorado accepts invitation to join Pac-10

WALNUT CREEK, Calif. -- The Pac-10 conference says Colorado has accepted an invitation to become the league's 11th member.

The conference announced its first expansion since adding Arizona and Arizona State in 1978 on Thursday. More teams could follow Colorado from the Big 12 to the Pac-10. Reports say Texas, Texas A&M, Texas Tech, Oklahoma and Oklahoma State could accept invitations soon.

Pac-10 commissioner Larry Scott announced in February that the conference was exploring possible expansion. He was given the authority last weekend from the schools to offer invitations to potential new members.
