Artur Boruc will not face action over complaints he threw a water bottle at Southampton supporters.
The alleged incident occurred during Saints' defeat to Tottenham last month - goalkeeper Boruc's second game for the club.
The Poland international was left out of Nigel Adkins' squad for the defeat at West Brom while an investigation was carried out.
And Adkins said: "The investigation has now been concluded to the satisfaction of the football club. Artur is now back in contention for the remaining fixtures."
Boruc will now compete with Paulo Gazzaniga for a start against Swansea on Saturday.
