Graham Turner will find it tough to make any changes to his Shrewsbury XI for the clash with Swindon.
Turner watched his side see off Premier League Swansea 3-1 in the Carling Cup on Tuesday having kept faith with the same starting line-up who disposed of Crewe last weekend.
And he is expected to stick with the same team for the visit of Paolo Di Canio`s Robins, who themselves caused a cup upset with their 1-0 triumph at Bristol City.
Turner will, however, warn his side not to fall into the same trap as they did after their similarly impressive 3-2 victory at Derby in the previous round, subsequently going on to draw at Burton and then lose to Oxford in their following matches.
Striker Tom Bradshaw returned to the bench for the first time in midweek having recovered from knee ligament damage.
But with the number of substitutes once again reduced from seven for Carling Cup matches to five, the Wales Under-21s international could have to fight it out with fellow forward James Collins to be included in the matchday 16.
Paolo Di Canio is likely to name an unchanged side having seen his charges cause a Carling Cup upset at Bristol City in midweek.
Di Canio recorded the most impressive result of his short managerial career to date as Town dumped their Championship opponents out of the League Cup on their home soil.
Striker Raffaele De Vita stepped off the bench at half-time to bag the only goal and could force Di Canio into a change, although the Italian may well again opt to keep faith with Alan Connell in attack.
Fellow forward Lukas Magera was a 75th-minute substitute at Ashton Gate but needs more match fitness before being considered for a starting berth.
Mehdi Kerrouche (hip) and Alberto Comazzi (hamstring) were fit to face City on Wednesday, the latter making the bench. Both are again in contention for Swindon`s first-ever trip to the Greenhous Meadow.
Captain Oliver Risser (groin) and defender Alessandro Cibocchi (ankle) remain sidelined.
