Leicester manager Micky Adams is undecided whether to play Paul Dickov, Frank Sinclair and Keith Gillespie in Saturday's game with Everton.
The trio played for the first time on Tuesday in a reserve game since being bailed on sexual assault charges after alleged incidents in La Manga.
Adams said: "I have to decide whether they are in the right frame of mind.
"I have to think about everything that has happened to them - and what they've done for me in past performances."
Adams added: "We will not wait until the internal investigation has been
concluded before bringing them back.
"We are fourth bottom of the Premiership with a very small squad and will
hear all sides of the story and, until we decide what disciplinary action we're
going to take, they are available.
"I keep saying this but at present all they have been guilty of is 14 days
before a game having a drink."
Southampton won the reserve fixture 3-1 but the three, booed throughout by the Saints fans, all completed 90 minutes.
Reserve team coach Peter Shirtliff told Leicester's website: "It was a good fitness exercise for all concerned."
Shirtliff added: "We got through without picking up injuries.
"Paul Dickov, Frank Sinclair, Keith Gillespie, Lilian Nalis and Peter Canero all got a full 90 minutes of action under their belts which they needed after a
lengthy period without a game."
Saints took the lead through Simon Gillett before Marian Pahars headed the
Tom Williamson pulled a goal back before Fitz Hall wrapped up the victory for
the home side.
The three Leicester players, who only returned to the UK on bail last week, will have to return to Spain if the case goes to court.
