Arsenal’s Declan Rice and Gabriel have trained before Tuesday’s Champions League quarter-final with Sporting.
Midfielder Rice, 27, left the England squad following a medical assessment during March’s international break and missed Saturday’s FA Cup quarter-final loss to Southampton.
Brazil defender Gabriel, meanwhile, was forced off with a knee issue after taking a knock during the defeat on the south coast.
Both players were involved in first-team training at the club’s London Colney base on Monday before Mikel Arteta’s side travel to Lisbon for the first leg.
Belgian winger Leandro Trossard also returned to training but Bukayo Saka was not involved after he also left the England camp early.
