Jonathan Sexton won his fly-half battle with Dan Biggar to help send Leinster to the top of the Guinness Pro12 table with victory over the Ospreys at the Liberty Stadium.

"Johnny did about 3.5km running, that's a positive," assistant coach Greg Feek said on Wednesday afternoon.

While Clermont and Toulon both suffered embarrassing defeats in the Top 14 at the weekend, Jonathan Sexton’s Racing Metro ground out an impressive 12-6 win in a wet and windy Bayonne.

Joe Schmidt has said that Ian Keatley is on standby in case Jonathan Sexton cannot play in the Wales clash on Saturday.

Ireland and Racing Metro are at loggerheads over the severity of Johnny Sexton’s thumb injury, casting the fly-half’s RBS 6 Nations campaign into doubt.
