Joey O'Brien has signed a new one-year contract extension with Bolton Wanderers.

The versatile midfielder is now tied down with the football club until the summer of 2011.

Manager Gary Megson said: "Joey has had a horrendous time with injuries and I wanted to give him one less thing to worry about while he goes through his rehab. You wouldn't wish the problems Joey has had, in terms of his physical well-being, on anybody.

"It is difficult when you are injured but when it's over a long period of time it is a process that mentally can cause as much of a problem as the physical one. We've given him that extra year because it's the right thing for an employer to do, especially at a football club."

O'Brien, 23, progressed through Wanderers Academy before making his first team debut in September 2004 in a Carling Cup tie against Yeovil Town.

In total he has made 70 competitive appearances for the club and has earned three caps for the Republic of Ireland.
