The scrum-half, capped 98 times for Ireland, has enjoyed a successful spell with the club and has been a key member of an aspiring squad.
Bath, currently sitting in third place in the AVIVA Premiership, say the 36-year old is still playing with the same tenacity and quick-thinking he displayed on the international stage and they have put his experience to good use this season.
Following the announcement of his contract extension, the former Munster scrum half said:
“Bath is a great place to be at the moment. There’s a lot of hugely exciting young players in the squad, and it’s a group that’s really building towards a bright future.
“I feel I still have a lot of rugby in me, and still enjoy getting out there and training and playing with the lads.
“I’m looking forward to the rest of this season and next, and seeing how far we can go.”
Mike Ford, Bath Head Coach, added: “Strings brings a lot of experience to our relatively young squad, and his absolute professionalism sets a great example to them.
“He’s not lost any of his enthusiasm or ability, making him a real asset for us, and we’re thrilled he’s agreed to stay for another year.”
