Dan Biggar’s return to the field after a clash of heads against Leinster has been questioned by an Irish neurosurgeon. The Wales fly-half missed a late kick in the Ospreys’ 20-18 defeat at home to Leinster on Saturday, minutes after being allowed back on following a head injury assessment (HIA).

The failure of the Welsh regions this season is in sharp contrast to the scene in Ireland, argues Robin Davey. Wasting golden opportunity has become a Welsh trait. It’s not only on the national front where Wales have fallen down this season – it’s much the same when it comes to the domestic scene, too. The Scarlets, though admittedly in a tough group, and the Dragons, both failed to get past the group stages of the European Champions and Challenge Cup, respectively.

The Guinness Pro 12 returns this weekend, but Phil Bennett argues the sense of drift and anti-climax is all too apparent. Instead of ending the season with a bang every year, the Welsh regions finish with a whimper. Thanks goodness for the Ospreys and the Scarlets, otherwise the Welsh rugby season would end in March every year. The Six Nations finished and continued Welsh interest in Europe was over before you could say “Josaia Raisque”.

Steve Tandy has admitted the Ospreys have blown a golden chance of silverware through their failure to be ruthless. Welsh interest in Europe ended for yet another season when the Ospreys followed the Cardiff Blues by making a mess of things in the first knockout stage.

Chris Gibbes says his Ospreys players must step up in the absence of skipper Alun Wyn Jones when they take on Stade Francais in the European Rugby Challenge Cup. Jones was ruled out of the quarter-final clash after injuring his shoulder during Wales’ defeat to France in the Six Nations. He is expected to be crocked for six weeks.

Ospreys head coach Steve Tandy has admitted he was embarrassed by their defeat to Treviso and branded it one of the worst during his five years in charge. The region – who face Stade Francais next week in the European Challenge Cup quarter-final – went down to a shock 13-5 defeat in Italy on Saturday night to lose ground on the top two in the Guinness Pro12.

Steve Tandy plans to reward his table-topping Ospreys with a week off in the sunshine after their hard-earned victory at Edinburgh. The region went top of the Pro 12 table after grinding out a 13-9 triumph in awful conditions in Scotland on Friday night.

Cory Allen has said he is leaving the Cardiff Blues for the Ospreys because he believes they can make him a better player. He has also stressed his belief he is joining a region with an ambitious head coach in Steve Tandy.

Cory Allen is being offered a “fresh start” by the Ospreys, according to coach Steve Tandy. Wales centre Allen is leaving the Cardiff Blues for the Liberty Stadium to replace Fijian Josh Matavesi, who will also move on at the end of the season to join Newcastle.

Munster captain Tyler Bleyendaal has insisted they always knew they would have the reserves to beat the Ospreys. Not for the first time the Irish province broke hearts when they snatched a late victory on Welsh soil – this time grabbing a 25-23 win late on to move back to the top of the Guiness Pro 12.

Keelan Giles could yet wing his way into Wales’ Six Nations campaign after being declared fit for the Ospreys. The lightning quick 19-year-old – who was left out of coach Rob Howley’s 36-man squad for the tournament because of a hamstring injury – has been picked to start for his region at home to Munster on Saturday.

Wales and Ospreys wing Eli Walker has been ruled out of the remainder of the season after undergoing back surgery. The 24-year-old has been sidelined since November when he suffered a foot injury during the Anglo-Welsh Cup win over Cardiff Blues, and a back injury delayed his return to action.
