Titterrell, 28, has been without a club since leaving Gloucester during the summer but has joined up with Leeds Carnegie.
Originally from Dartford, Titterrell first rose to prominence during his seven years at Sale Sharks. He made his debut for the Sharks in 2001 and in 2004 gained his first cap for England against the All Blacks in Auckland. In total, he has five caps for England and was also selected to tour with the British and Irish Lions in 2005. The highlight of his time at Sale was in helping the Sharks to win the Guinness Premiership for the first time in their history in 2006.

In 2007, he moved to Gloucester and made 30 appearances for the Cherry and Whites in two seasons before leaving Kingsholm this summer.

Commenting on the signing Head Coach Neil Back said, "We are delighted to have brought in a player of the quality and experience of Andy Titterrell. His signing has filled a gap in our squad and it will strengthen the team. Recently Rob Rawlinson and Phil Nilsen have both been suffering from injuries which left us with just one fit hooker in Vili Ma'asi. Our young Academy hooker in the first team squad, Scott Freer, has been ruled out for the season following a knee reconstruction so Andy's signing is a timely one.

"He has made over 150 appearances in the Guinness Premiership with Sale and Gloucester and that will be invaluable for us," added Back.

Commenting on signing for Leeds, Titterrell said, "I am pleased to be back in the Guinness Premiership. Having met with Neil Back and Andy Key, I have been impressed with the set up here at Leeds Carnegie and I am looking forward to playing a part in helping them move up the table."
