Ruud van Nistelrooy's Manchester United future is in doubt after he drove away from Old Trafford three hours before the Premiership finale with Charlton.
Will Ruud van Nistelrooy still be at Old Trafford next season?
And manager Sir Alex Ferguson confirmed the Dutch striker's actions will be discussed at a board meeting this week.
He said: "There have been a couple of issues during the week that concerned us in terms of the spirit of the club.
"On such an important day, I felt that Ruud should be left out. We will be discussing it with club directors."
Van Nistelrooy was at Old Trafford on Sunday morning and is understood to have been fully fit and expecting to play alongside Louis Saha because Wayne Rooney is sidelined with a broken bone in his foot.
But he had left the ground by the time the team ran out and Giuseppe Rossi was selected to play alongside Saha.
Van Nistelrooy, 29, has spent much of the final third of the season on the bench and the latest events raise more questions about his future.
Recent newspaper speculation has suggested that Van Nistelrooy may leave United in the summer - but Ferguson has not made any comment on his future.
