Linfield captain Michael Gault has agreed a two-year extension to his contract with the champions, which will keep him at the club until May 2014.
Gault will revert from full-time to part-time status, in line with the Windsor Park club's current policy.
The midfielder has been awarded a testimonial year in 2013 as part of his new deal.
"Michael is proving to be a great leader on and off the pitch," said Linfield manager David Jeffrey.
Gault has played for the Blues since 2002.
