Steven Reid has signed a new two-year contract which will keep him at The Hawthorns until the summer of 2014.
The 31-year-old's current deal was due to run out this summer but the new offer is a reward for the form he displayed before recently undergoing ankle surgery.
The West Bromwich Albion sporting and technical director, Dan Ashworth, said: "We're delighted to have agreed a new contract with Steven. He's had a good, solid season and proved he is still more than capable of playing Premier League football. He is also a fantastic person to have around the training ground."
