Cardiff City head coach Brian Barry-Murphy says top scorer Yousef Salech is "not close" to a return from injury.
Salech damaged ligaments in his neck during Cardiff's 1-1 draw with Stockport on 24 January.
The 24-year-old had a hospital scan to determine the severity of his neck injury, and while it was determined to be not serious it has kept him out of training since.
Asked after Cardiff's 3-1 win over Luton whether a return was near, Barry-Murphy said: "He's not close.
"Yousef was here today, but he hasn't rejoined the team for training yet, until he does that we won't really have a time scale.
"With an injury of that nature you have to be really patient to make sure his neck and surrounding areas are ready.
"At the moment he's not ready."
Salech's absence has not slowed the Bluebirds down, with Saturday's win over Luton moving them four points clear at the top of League One.
Cardiff have also not seen a drop in the number of goals scored, with the Bluebirds scoring two or more goals in each of their four games since.
Barry-Murphy's side are back in action on Tuesday evening against AFC Wimbledon (19:45 GMT), as they look to continue their unbeaten run of 11 League One games and 11 home games.
