According to Daily Mail, the new deal adds three-and-a-half years to Henderson's existing contract, which had been due to expire in 2028. The move comes after former Palace manager Oliver Glasner attempted to bring Henderson to Nottingham Forest during the summer transfer window, lodging an enquiry just three days before the deadline that was swiftly rejected.
Henderson has instead committed his prime years to Selhurst Park, with talks over an extension first reported in July. The 29-year-old became club captain last season and led Palace to Uefa Conference League glory, a campaign in which he also played a crucial role in the club's FA Cup triumph, keeping clean sheets in the quarter-final, semi-final and final.
He made 52 appearances for Palace last season and kept 18 clean sheets, underlining his importance to a side that enjoyed the most successful campaign in the club's history. Henderson joined from Manchester United in 2023 for an initial £15 million, having previously spent time on loan at Sheffield United and Forest, and has since established himself as a firm fan favourite at Selhurst Park.
The goalkeeper is currently sidelined with a foot injury, having played through the issue for the first three matches of this season before it forced him out, and is expected to return after the international break. His new deal underlines the faith Palace's hierarchy retain in him despite the injury and a stuttering start to the season for Pierre Sage's side.
Henderson capped a strong year for club and country by winning bronze with England at the World Cup this summer, starting in the third-place play-off. His new contract ties down one of the club's most important figures for the long term, just as Palace look to build on a period of unprecedented success under new management.
The move also represents a significant show of faith from Palace's board, who have backed Henderson with the security of a long-term deal despite a difficult start to the season that has seen the club win just one of their opening four Premier League fixtures.
Keeping hold of a proven leader between the posts, particularly given the goalkeeper's importance during last season's cup exploits, is regarded internally as a priority regardless of short-term results on the pitch.
