The Egypt captain was spotted taking part in team training at Liverpool's AXA Training Centre base in Kirkby on Tuesday - normally a sign of a full recovery from injury.
The side's top goalscorer has been missing from club action since the New Year's Day win over Newcastle United due to his participation in the Africa Cup of Nations with Egypt, where he later sustained a muscle injury against Ghana.
Following his injury, Salah was flown back from the tournament and has been undergoing rehabilitation and a tailored training programme.
Salah's potential return comes as a huge boost for manager Jurgen Klopp, whose side has suffered a string of absences in recent matches.
Klopp had emphasised that Bradley would be given the necessary time with his family and was under no pressure to rush back to training. However, all three players were spotted back at the training ground on Tuesday, signalling their readiness to rejoin first-team action.
Despite the return of several players, there's still uncertainty over the fitness of Trent Alexander-Arnold, Ryan Gravenberch and Dominik Szoboszlai, who are nursing injuries.
Gravenberch, in particular, felt discomfort in his groin during Saturday's warm-up, raising doubts over his availability for the upcoming match.
As the team continues preparations for the Brentford clash, Klopp will be hopeful of welcoming back more players to strengthen his squad.
With four days left until the match, there is ample time for further developments as the team strive to maintain their position at the top of the Premier League table.
