Despite displaying impressive form for his club City, Richards played just once under former England boss Fabio Capello. But the right-back will get a chance to impress when the Three Lions host Netherlands in a friendly next Wednesday.
Campbell, meanwhile, is a shock call-up having been dogged with injury, making just three Premier League starts for Sunderland last season following a serious knee injury. The forward has, however, impressed since making his return in January this year, scoring twice in five outings for Martin O'Neill's Black Cats.
O'Neill told the club's official website: ''There are some terrific players there and getting a place in the squad is extremely difficult. He has only had a couple of games back. It's a boost, even just to be involved for a few days.
''It's fantastic. Whether he does or doesn't play, to me, is immaterial at this stage. The news is a great boost - I think it would have been a bit of a surprise for him. If he gets the opportunity, it would be great to take it.''
Campbell himself responded to his call-up via Twitter. He tweeted: ''Absolutely delighted to be part of the England team. Been the longest and hardest 18 months of my life and feel truly honoured to be given a chance.''
Neither Rio Ferdinand nor Frank Lampard have been selected, and the presence of Steven Gerrard suggests the Liverpool midfielder will gain the captain's armband, stripped from John Terry earlier this month.
In addition to Campbell, the only other uncapped member of his squad is Manchester United's Tom Cleverley, although he was selected for the squad to play Netherlands in August, a match which was postponed, and the subsequent Euro 2012 qualifiers with Bulgaria and Wales.
