Charlie Austin will play no part for Swindon against Exeter after he left the club.
The striker agreed to join Championship side Burnley on Friday afternoon after a handful of rival teams jostled for his signature.
Manager Danny Wilson`s immediate concern revolves around whether any move will happen before Saturday`s clash against the Grecians.
Fellow forward Vincent Pericard is battling to recover from the knee injury which forced him to miss Tuesday`s goalless draw against Tranmere.

Recent signing Aden Flint has finally received clearance from the Football League and could make his debut.
Exeter manager Paul Tisdale will have to decide whether to recall Ryan Harley.
Harley, who signed for Swansea last week, has rejoined the Grecians on-loan for the rest of the season and after missing last week's win over Walsall, Tisdale will have to decide whether to recall his star midfielder or keep a winning side.
Goalkeeper Ben Hamer, who signed on-loan from Reading last week, is set to continue between the sticks after a successful debut against the Saddlers.
Striker John O'Flynn has staked his claim for a recall to the starting line-up after coming on as a substitute to win a penalty last weekend and scoring for the reserves in midweek.
Defender Troy Archibald-Henville also scored on reserve-team duty and is pushing for a starting place.
