GLASGOW WARRIORS' title run in hopes have been dealt a blow by the news star Mark Bennett is out for the remainder of the season.

The Scotland international picked up a shoulder injury playing in the RBS Six Nations earlier this year with it hoped he would be able to return for Glasgow's title run in.

However, the centre's campaign is now over after it was revealed he needed to go under the knife to correct the problem.

A statement from the Scotstoun club read: "Following an MRI scan at BMI Ross Hall Hospital, it was determined that an operation was required.

"Mark has now undergone surgery and will begin a period of rehabilitation with the aim of being fit for selection for the Rugby World Cup."

There was also an injury update in respect of DTH van der Merwe who sustained a hand injury during last Friday's win over Cardiff Blues.

The Canadian has also had an operation and is set to undergo a period of rehab in a bid to get him back in time for Glasgow's play-off push.

The statement added: "The Canadian international has undergone surgery under the care of orthopaedic consultant Mr Doug Campbell, who specialises in hand/wrist surgery.

"DTH will now commence a period of rehab with the medics and will be working towards a possible return before the end of the season.

"The club would like to thank match doctor Andrew Murray and the A&E at Western Infirmary in Glasgow for their assistance on Friday night."

TENNIS: World number two Roger Federer and defending champion Stan Wawrinka both suffered third-round defeats at the Monte Carlo Masters.

World number nine Wawrinka, the 2014 Australian Open champion, beat fellow Swiss Federer last year to win his first and only Masters 1000 title.

But he lost 6-1, 6-2 to Bulgaria's world number 11 Dimitrov in 54 minutes.

Second seed Federer was beaten 6-4, 7-6 (7-5) by Frenchman Gael Monfils, the world number 18 and 14th seed.

GOLF: Rory McIlroy's powers of persuasion have resulted in US Open champion Martin Kaymer, former world number one Luke Donald and American Ryder Cup star Patrick Reed in confirming their participation in the Dubai Duty Free Irish Open.

McIlroy's foundation is hosting the event at Royal County Down from May 28-31 and the world number one has been a major influence in attracting a top-class field, who will compete for a prize fund of 2.5million euro (£1.8million), an increase of 25 per cent from last year.

Reed let the cat out of the bag on the final day of the Masters at Augusta National, also revealing he would compete in the BMW PGA Championship at Wentworth the week before.

But the addition of Kaymer and Donald means the tournament will feature five players who have been world number one - McIlroy, Donald, Kaymer, Ernie Els and Lee Westwood - and eight major champions in McIlroy, Els, Kaymer, Darren Clarke, Padraig Harrington, Graeme McDowell, Paul Lawrie and Jose Maria Olazabal.

Ryder Cup captain Clarke said: "Rory has pulled in a lot of favours and it's a testament to the high esteem Rory is held that it's going to be the strongest field for a long time.

"It's a huge positive for the European Tour to have such a tournament on one of the best golf courses in the world.

"I have always wanted to win the Irish Open but have not managed to play well in it that often. Hopefully being back at Royal County Down I will have a decent week this year."

Donald, who last played in the Irish Open in 2004, said: "My performances and results have been getting better and better recently and I am feeling very positive about a huge summer of golf ahead.

"The Irish Open will be a big part of that and I am looking forward to playing Royal County Down and some really 'old school' links golf - I think the links golf factor will add a lot to the event and it's looking like it's going to be a great week."

Kaymer added: "There is definitely a good feeling about this year's Irish Open and I think Rory has done a great job to get such a great field for the event and to create a really nice atmosphere about the tournament."
