Harwood-Bellis, 22, joined Southampton on a permanent basis last summer after helping the Saints to promotion during a season-long loan move from Manchester City in the 2023-24 season.
He has made 13 appearances in all competitions for Russell Martin’s side this season, scoring three times.
Hall, 20, joined Newcastle in a £28m deal from Chelsea last summer after spending the previous campaign on loan in the north east of England.
The left-back has appeared in all 10 of Newcastle’s Premier League matches this season, starting seven of them.
“They’re both players who have played a lot of minutes this season and have shown they can consistently play in the Premier League at a high level,” said Carsley.
“Players that I both know really well. I’ve known Taylor from Man City and captaining the under-21s, having a successful summer with promotion and playing in the Premier League week in and week out, he’s a player that really deserves it.
“He’s an outstanding captain and a brilliant example to the rest of the players in the under-21s squad.
“Lewis is a player who’s taken his time to settle in – he’s high quality, left-footed and a player who deserves to be in and has shown he can be really consistent.”
Liverpool midfielder Curtis Jones has earned a call-up after he pulled out of October’s squad for the birth of his child.
The 23-year-old, who won the U21 European Championships under Carsley in 2023, is yet to make his debut for the national side.
“Curtis is an all-round player, who plays in various positions,” said Carsley.
“He is a player I highly rate, he’s one of the best I’ve worked with in terms of ability. He is showing consistency at a high level now. He can score goals, assist and is player we’ve had a lot of success with in the past.”
