Everton winger Aaron Lennon is among the players to return to the Premier League club for pre-season preparations.
The 30-year-old was detained by police in May under the Mental Health Act over concerns for his welfare.
He was taken to hospital “for assessment” but was expected to make a full recovery in the short term.
Long-term injury absentees Seamus Coleman and Yannick Bolasie were also at the Finch Farm training ground.
All three players were part of a photo gallery posted by the club showing the squad’s return to the training complex.
