Morgan Schneiderlin and Kevin Mirallas were reportedly sent home from an Everton training session on Saturday.
According to the Liverpool Echo, the duo appeared disinterested which tested the patience of coach Duncan Ferguson, who told them they should go inside if they were not going to bother.
Both players then apparently walked out of the session, before being told to go home.
Neither player featured on Sunday as the Toffees battled back from 2-0 down to beat Watford at Goodison Park.
