The Chelsea star followed his sibling Nathaniel in representing England, emerging as the twenty-first duo of brothers to play for the England side.
The Chelsea defender is set to link up with the Three Lions selection to cover for injured Crystal Palace centre-back Marc Guehi.
The 26-year-old is scheduled to link up with the national side for England's remaining World Cup qualifiers against Albania and Serbia, but it has still not been officially announced.
The England team have already qualified for next summer's competition.
Chalobah received his maiden call-up under England head coach Thomas Tuchel in the month of May and then earned his first cap against Senegal.
In the month of September, Tuchel remarked Chalobah was unfortunate to be left out from the selection for qualifiers against Andorra and Serbia, and additionally didn't call him up for the next October fixtures.
Tuchel has been an key influence in Chalobah's development, having awarded him his Chelsea first-team bow in 2021.
Chalobah has featured in nearly all matches for Chelsea in the current campaign, with the club third in the English top flight, in the Carabao Cup quarter-finals and in the league phase of the Champions League.
Guehi suffered a injury to his foot in Crystal Palace's Europa Conference League win over AZ Alkmaar last week.
There are likely to be additional call-ups to the squad. Newcastle manager Eddie Howe has announced that both attacker Anthony Gordon (hip) and goalkeeper Nick Pope (concussion symptoms) will withdraw from the national team.
