PHILADELPHIA (AP) - Navy is still on board for Big East football in 2015.

Athletic Director Chet Gladchuk says nothing has changed with the Midshipmen's ``attitude or ambition'' toward joining the unsettled conference in 2015. Navy agreed last year to give up more than 130 years of football independence to join a conference that is in the middle of a massive overhaul.

Navy has been playing football since 1879 without conference affiliation. Gladchuk says ``independence is no longer an option for us'' and says the Big East is still the right fit for the program.

Louisville on Wednesday became the fourth school in 15 months and seventh in the past decade to leave the Big East for the ACC. The Big East also lost Rutgers last week. The reinvented conference added Tulane and East Carolina this week.
