Swindon Town midfielder Ben Gladwin is set to undergo knee surgery on Monday which is likely to keep him sidelined for four weeks.
The 22-year-old sat out Town's last game, a 3-1 victory over Chesterfield on 17 January.
And he did not travel to Tenerife for the team's warm-weather training, which was arranged following the postponement of Saturday's game against Bradford.
The League One leaders return to action against Sheffield United on 31 January.
Gladwin signed a new contract with Mark Cooper's side last month and has made 21 appearances this season, scoring twice.
