Ospreys star Sam Underhill remains uncertain whether playing in Wales will block his England hopes.

Underhill, 19, wants to pursue England honours rather than try and qualify for Wales on residency grounds but his decision to play this side of the border means he has so far been overlooked.

The RFU have strict rules on whether England coaches can turn to players based elsewhere and Grand Slam winner Eddie Jones has admitted he is still in the dark over Underhill.

The issue has become more urgent following the long-term injury suffered by Wasps flanker James Haskell, who has been ruled out for six months with a foot injury.

That could open the door for Underhill – who moved to Wales to study – but if the policy of non-selection except in “extraordinary circumstances” remains then the Opsreys could find pressure being heaped on one of their most promising players to quit the region and re-locate back in England.

Asked if there had been a clear directive from the RFU regarding the eligibility of the former England under-18 player, Jones said: “Yes and no”

“‘Yes’ is that I don’t think that his position has changed, and the ‘no’ is that we still need to investigate. We’ll just wait and see.”

It was suggested last season that Premiership clubs could block the move to select Underhill, who shifted base to Swansea to study for his degree.

If Underhill does remain with the Ospreys, then fans will see less of him – and others – on a Sunday after Guinness Pro12 organisers decided to scrap the regular fixtures on that day.

Broadcasters S4C have moved their regular slot from Sunday afternoon to Saturday at 7.30pm, even though Sky show their live games at 3.00pm and 5.30pm on the same day.

In return for allowing S4C to use a Saturday window, Sky will have the pick of the matches each weekend ahead of S4C and BBC Wales.
