Iain Henderson in race against time to make Six Nations showdown with Wales
Ulster's Iain Henderson remains a big doubt for Ireland's Six Nations clash with Wales at the Aviva on Saturday (2.15pm).
The lock was taken off at half-time in the side's big win over Italy almost a fortnight ago after experiencing tightness in his quad and hamstring.
But despite the early exit being described as largely precautionary, he didn't train fully yesterday with Tadhg Furlong also missing parts of the session.
"Iain Henderson, a bit like Tadhg, is hitting his markers and pushing in the right direction and we will assess how he pulls up after two hard days of work at training," said Ireland's defence coach Andy Farrell at Carton House.
"There is not a risk, we wouldn't take risks. We back the full squad that we have got.
"We have quality players across the board, so we will make the right decision come Wednesday/Thursday," Farrell added.
Ahead of their own game against Scarlets on Saturday, Ulster have ruled out winger Craig Gilroy.
The side's top try-scorer this season is struggling with a rib injury picked up against Edinburgh last week.
There has been no indication yet whether John Cooney will be released back to the province, regardless of whether he makes Ireland's matchday 23, while both Rob Herring and Johnny McPhillips are doubts but took some part in training yesterday.
