Premier League - Smalling named in U21 squad
Smalling has played nine times for the U21s, but was touted as a possibility for Fabio Capello's senior squad to face Wales in a European Championship qualifier on March 26 and the friendly against Ghana at Wembley Stadium three days later.
He was included for England's friendly match with France at Wembley Stadium in November, but was an unused substitute as England lost the match 2-1.
Celtic striker Gary Hooper is rewarded for his 13 goals in the Scottish Premier League with a first call-up after head coach Stuart Pearce attended the recent Old Firm match with Rangers in the Scottish Cup.
Wolves midfielder Mark Davies is also named for the first time.
England visit Viborg in Denmark on March 24 before hosting Iceland at Preston's Deepdale on March 28.
Pearce has named a 31-man squad as he assesses his options before the European U21 Championship in Denmark in June.
"There are one or two fresh faces in there such as Gary Hooper and Mark Davies but in the main the majority of the players are well known to us and have been involved in the qualifying for the tournament," Pearce told the FA's website.
“Now’s the time for all of the players to impress in the minds of the coaching staff that they want to be the ones stepping on to the plane. At the end of this meet-up I need to be able to make some final decisions about my squad – and I will.
“Both of the teams we’ll face will be in the Championship in June so there can be no better warm-up opportunity for us and there will be no underestimating anyone on our part, and I expect the opposition will be thinking much the same about us.”
