Henderson's intervention came in his 99th appearance for the club in all competitions.
Of the 19 goalkeepers who have made 99+ appearances for Palace, Henderson currently has the third best clean sheet percentage – behind only John Burridge (40.2%, 1978-1980) and Jack Alderson (35.1%, 1919-1924).
However, only 42 of Burridge's appearances were when Palace were in the top-tier, and Alderson's were all when Palace were in the Southern League, Division Three or Division Two.
Second
Of the six Palace goalkeepers to have played 40 or more matches for the club in the top-flight, Henderson has the second-best clean sheet percentage (30%) behind Nigel Martyn (32%).
Seven
Sunday's stop was Henderson's seventh penalty save in a Crystal Palace shirt, including his stops at Aston Villa (against Ollie Watkins) in November 2024; three penalties at Wembley (against Omar Marmoush in the FA Cup final last season; and two in the Community Shield win over Liverpool earlier this campaign, against Alexis Mac Allister and Harvey Elliott).
