Crystal Palace midfielder Jonny Williams will stay at Ipswich Town until the end of the season.
However, Tony Pulis does have the option of recalling the 20-year-old Wales international at 24 hours notice.
Williams, who joined the Championship outfit on an initial one month's loan, has made six appearances and helped guide the Tractor Boys to within two points of the play-offs.
He told the Ipswich website: "I'm delighted to be extending the loan because I've really enjoyed my time at Ipswich.
"It's been a great experience for me and I've loved working under the manager and assistant Terry Connor."
He added: "I'm excited to get back training with the lads and playing my part as we try and push into the play-offs."
