Capello does not pick players who are not club regulars, but Foster's Carling Cup final display in United's win over Spurs earned him a spot in the squad.
The 28-year-old King also played in that game at Wembley, while the defender's last England appearance was in June 2007.
King suffers from a debilitating problem in his right knee that prevents him from doing any training sessions with his Spurs team-mates during the week.
The only contact he has with them is on the day before a game when King watches training to learn the moves he will be part of on match day.
King's Spurs team-mate Aaron Lennon, who won the last of his nine caps against Andorra two years ago, is included, reflecting his recent fine form for Tottenham.
Lennon will compete with Shaun Wright-Phillips and David Beckham for the position on the right of midfield.
But Aston Villa duo Ashley Young and Gabriel Agbonlahor miss out, neither of whom keep their places following last month's friendly defeat to Spain in Seville.
Wayne Rooney and Steven Gerrard back for the first time since the qualifying win in Belarus last October, while Rio Ferdinand is fit after missing the Seville reverse with a stomach bug.
