Tickets for Boro's Emirates FA Cup quarter-final match against Chelsea at the Riverside have now sold out.
The match is a 5.15pm kick-off on Saturday 19 March.
The remaining tickets went on sale to supporters with 11 or more Priority Points earlier this evening, and were quickly snapped up.
It's a second successive home sell-out for an Emirates FA Cup match at the Riverside after a capacity crowd watched Boro's extra-time win over Spurs in the last 16.
