Adams speaking at Tavistock AFC's last night
Derek Adams has revealed Josh Simpson is back in training and despite his Crystal Palace debut Hiram Boateng may still return to Home Park.
During a session answering fans' questions at a special event organised by Tavistock AFC tonight, the Scot also said it would prove difficult to permanently sign Craig Tanner and Jordon Forster next season.
Simpson, 28, has been missing from the Argyle first team since salvaging a draw at Bristol Rovers last month with a late equaliser, but could be back in contention before the month is out after returning to
Plymouth Argyle: Derek Adams points to the importance of competition for places
"There is still a possibility, yes. That door has not been closed by myself or Crystal Palace, but it depends on their injury situation," said Adams.
"While Hiram is getting around their squad and even the team it's benefitting him.
"They have players coming back regularly, so it is still a possibility."
One fan asked Adams if Tanner, Forster or fellow loanee Oscar Threkeld will return to the Green Army as permanent fixtures next season.
The 40-year-old boss said Tanner was still under contract with Championship Reading, Forster has now been offered a new deal with Hibernian in the Scottish Premier League and Threlkeld was still to be considered by Bolton Wanderers for a new contract.
"That (keeping them next season) could be difficult, but you never know," he said.
"All the loanees have performed very well for us this season and you should never say never, but we have to progress them now before looking at that in the future."
Targets have already been found for the summer transfer window too, said Adams, who revealed he has a database in place for every target depending on scenario come the end of the season.
He also said he wanted more leaders in the side: "We could do with more leaders because every team needs 11 leaders on the pitch."
With Simpson back in training, Adams confirmed Tyler Harvey was the only remaining injury doubt.
"To have one injury at this stage of the season is very good. You want everybody fit with a full choice of players to choose from," he said.
"We have a stronger bench now than at any other stage of the season."
In a wide-ranging session with a group of more than 50 supporters, Adams admitted the Home Park surface had caused him and the team problems this season, but nothing more could be done until the end of the season.
He also said Newport County's Rodney Parade was the worst pitch Argyle had visited this season, largely because of the rugby played on the surface there.
