Last Saturday Percy Harvin made only his second appearance of the season for the Seattle Seahawks, and he is now facing a battle to be available for his third.
The wide receiver had been out of action due to hip surgery, and the recovery process which followed, and had only returned to the Seahawks line up in time for the playoffs.
But after making a fairly successful comeback, helping his team take up a commanding position against the Saints in the divisional playoff game, Harvin left the field with a suspected concussion sustained after a collision with Saints safety Malcolm Jenkins.
Since then he has been a major doubt to play any part in the Seahawks-49ers NFC Championship game this weekend.
And today the Seahawks confirmed that he had not taken part in practice and the medical staff are still unsure if he will be cleared to play.
With concussion a major talking point in the NFL at present, Harvin has to meet an NFL mandated concussion protocol before going any further.
