Doak confident over Ferris fitness

Ulster assistant coach Neil Doak is confident that Stephen Ferris will be fit to face Edinburgh in Friday's Pro12 game at Ravenhill.

Ferris has been struggling to overcome a back spasm in recent weeks, but is set to start against the Scottish outfit.

Meanwhile All Black prop John Afoa says the Ulster players want to lay down a marker to their Pro12 opponents by maintaining their unbeaten record.
