Oxford goalkeeper Wayne Brown has signed a new two-year contract with the club.
Brown, who made his 500th career appearance this season, will combine playing with a new coaching role during the 2012/13 campaign.
The 35-year-old told the club's official website: "I have really enjoyed my time at Oxford and I am pleased to have extended my stay. It is an ambitious club and we will look to build on where we are at the moment.
"I feel I still have something to offer as a player but at the same time I see coaching as my future and I could not ask for a better person to learn from than Alan Hodgkinson."
Us boss Chris Wilder added: "I think the goalkeeping situation is in very good shape. Wayne has proved a more than able deputy to Ryan Clarke and with young Max Crocombe hopefully developing more next season it means we are well covered.
"Wayne has been moving towards coaching and will step that up but as we saw last season he still has plenty of ability and we know he is more than capable when we need him to step up into the team."
