Sean Cavanagh says Tyrone's defeat by Dublin and failure to make the Division 1 Football League semi-finals means the team will have to "go back to the drawing board".
The Red Hands paid for conceding three first-half goals as Dublin clinched a one-point win at Omagh which put the All-Ireland champions into the semi-finals and ended Tyrone hopes.
"It's a big setback. We were here to get to the league semi-finals. We saw how getting to the league final last year put us in good stead for the championship," said the Tyrone captain.
