HULL City captain Robert Koren and striker Gedo are both struggling to prove their fitness as the clock ticks down towards Saturday's crunch clash with Barnsley.
The Tigers head to Oakwell knowing a win would guarantee promotion to the Premier League, but Steve Bruce appears set to be without two of his most potent attacking weapons.
Skipper Koren, who is City's top goalscorer with nine goals this term, is yet to resume training since he suffered a calf strain in the 1-0 loss at Wolves.
A light session is planned for the Slovenian today but the Tigers' medical team only offer a "50-50 chance" of Koren recovering in time to face the Tykes.
The prospects of Gedo featuring at Oakwell appear even less promising.
Although the Egyptian striker declared himself fit to face Bristol City last time out, a lack of sharpness was clear in a below-par performance.
Gedo missed the fixtures with Ipswich Town and Wolves after aggravating a historic foot injury earlier this month and Bruce will be reluctant to take a second chance on the striker given the limitations revealed last Friday.
City are unwilling to rule either player out before travelling to an overnight base tomorrow, but Bruce may struggle to find room in his starting XI for either player.
The return of Corry Evans from a two-game suspension will boost City's midfield options and allow the Tigers boss to return to a trio that has previously served him well.
With Evans deployed in a holding role and flanked by the industry of Stephen Quinn and David Meyler, that three-man midfield was credited with inspiring City's best performance of recent weeks when winning 2-1 at Ipswich Town a fortnight ago.
The same trio also worked in unison during the Tigers' December purple patch, when 16 points were claimed from a possible 18.
Bruce's greatest dilemma for the trip to Barnsley will come in attack.
With Koren and Gedo, who have scored 14 goals between them this season, unlikely to be risked, Bruce will have to select from either Jay Simpson or Matty Fryatt to partner George Boyd in City's forward line.
Fryatt was preferred in the 0-0 draw with Bristol on Friday, his first Championship start for 356 days, but faded as the contest wore on.
Simpson cannot offer the same goal-threat but his hard-working style and hold-up play may tip the scales in his favour to face a Barnsley side in desperate need of points to boost their survival hopes.
City's last two away wins, a 1-0 triumph at Huddersfield and a 2-1 victory at Ipswich, both had Simpson and Boyd paired in attack.
The Tigers will depart for their South Yorkshire base tomorrow afternoon where they will wait for their Saturday demands to become clear.
Third-placed Watford's televised clash at Leicester could see City promoted if the Hornets were to lose against Nigel Pearson's men. A win or a draw for Watford, however, would need the Tigers to match their rivals' result to begin a promotion party at Barnsley.
