Ulster's Dan Tuohy has been ruled out of the entire Six Nations championship and may miss his province's Heineken Cup quarter-final with Saracens.
Tuohy broke his arm only minutes after coming on as a second-half replacement in Saturday's win against Wales and after undergoing surgery yesterday, Ulster confirmed a comeback date of between eight to 10 weeks.
This will leave the English-born lock (below), so impressive in his Six Nations debut against Scotland, with a race against time to be fit for the crunch Ravenhill clash against Saracens on April 5.
Ulster also have question marks over fellow lock Lewis Stevenson who sustained a forced flexion of his neck in the game against Ospreys last Friday evening.
He underwent an MRI scan yesterday and will be reviewed later in the week to determine his availability for the Scarlets game.
Darren Cave is also a doubt after he suffered a hyperextension injury to his left knee last Friday, but he trained yesterday and is still expected to be available for this weekend.
Meanwhile, the new Ravenhill Stadium will be officially opened on Friday, May 2 when Leinster hit Belfast in what should be a very important Pro12 game which could decide the Top Four play-offs.
The stadium will host the Heineken Cup quarter-final between Ulster and Saracens on April 5 and following that game, the finishing touches will be carried out on the grandstand ahead of the official May opening.
Munster forward Billy Holland has penned a new two-year contract and Ian Nagle has joined Premiership side Newcastle Falcons on a short-term loan.
"I'm delighted to have signed on for another two years," said Holland. "With such a young and exciting squad the future is bright here at Munster and I'm glad to remain involved. Having worked so hard to get where I am, I am keener than ever to push on and challenge for starting spots."
Nagle will join Danny Barnes on loan at English outfit Newcastle.
"Newcastle, who are currently struck with injuries, made contact with a request and we were happy to accommodate them," said coach Rob Penney of the three-month deal. "Ian departs with our best wishes and we believe it'll be a beneficial experience for him."
