Donegal pose no surprises for McIver

Derry manager Brian McIver says there will be "no unknown factor" for his players against Donegal in the Ulster Senior Football Championship semi-final on Saturday at Clones (19:00 BST).

The Oak Leaf county have not recorded a championship victory over Donegal since 2008, losing all four subsequent meetings including last year's first round tie in Celtic Park by 1-11 to 0-11.

McIver has stated Derry will have to play their best football in several years if they are to deny Donegal a fifth straight Ulster final appearance.
