Tino Livramento made a successful return with Southampton B on Friday night.
The wing-back has been out for 12 months with an ACL injury and featured in the B team's 2-0 win against Stoke City.
The 20-year-old suffered the ACL injury in the 2-2 draw at Brighton in the Premier League last April, suffering a setback in January that delayed his return.
Before the game, Saints manager Ruben Selles said: "Tino Livramento is playing today for the B team as part of his rehab and hopefully, all going well, he will then be with us."
