Alex Revell is unavailable to play in Swindon's FA Cup first-round tie against Woking while Tope Obadeyi's involvement is also highly unlikely.
The strike duo are on loan from Southend and Bolton respectively and while Revell has not been granted permission to play by his parent club, manager Danny Wilson will be trying to the last to confirm Obadeyi's availability although his chances appear slim.
Fellow forward Charlie Austin is already cup-tied having featured earlier in the competition for Poole Town but on-loan Celtic pair Simon Ferry and Ben Hutchinson can feature.
But Wilson also has problems elsewhere within his ranks with defender Lecsinel Jean-Francois suspended having picked up his fifth booking of the season in last weekend's 4-1 triumph at Tranmere. Jonathan Douglas also serves the final match of his four-game ban.
Midfielder Alan O'Brien (hamstring) continues to ease his way back into the action after a lengthy period on the sidelines but whether he is in Wilson's matchday 18 remains to be seen.
Winger Lloyd Macklin remains sidelined with a fractured leg as Swindon look to banish the memory of last year's first-round defeat at Histon.
Woking have no major injury concerns as they prepare for the match.
Substitute goalkeeper Matt Pegler is battling to recover from an arm injury but it is not as bad as first feared and he could take his place on the bench at the County Ground.
Striker Moses Ademola has returned to full training but still lacks the match fitness required to complete 90 minutes and could join Pegler on the bench.
Midfielder Mark Ricketts and defender Jon Boardman are struggling with slight knocks but should be okay.
The Cards are currently flying high in fourth place in the Blue Square South and will travel to Wiltshire in high spirits having lost just once in 10 away games so far this season.
Manager Graham Baker told the club's official website: "Every year, in every round, there are surprises and there's no reason why it couldn't be us this time.
"We've been playing well away from home and will be doing our best to make a real game of it. It will be difficult though."
