Cardiff City striker Yousef Salech has flown home to Copenhagen for personal reasons.
Salech returned to training last week following a neck injury sustained during the League One leaders' 1-1 draw with Stockport on 24 January.
The 24-year-old had a hospital scan which determined the injury was not serious.
Although Salech is back in training, he is still not ready to play.
"He's back home in Copenhagen. Some personal issues with his family, so he's at home in Copenhagen," said Cardiff head coach Brian Barry-Murphy.
"He'll return to us on Monday or Tuesday and crack on with his rehabilitation."
Meanwhile, forward Isaak Davies could feature in Saturday's League One trip to Doncaster Rovers (15:00 GMT) having been out with concussion.
Midfielder David Turnbull, however, will miss the game with a hamstring strain he sustained during last Saturday's 5-2 defeat at Plymouth Argyle.
"Isaak has trained fully this week, so fingers crossed he'll be available," said Barry-Murphy.
"David Turnbull came off with a hamstring injury at half-time at Plymouth and the suggestions are it's not a serious issue, but he hasn't trained as such. I'd say the weekend will come too soon for him.
"But apart from that, all the players who were involved at the weekend should be good."
