Luongo likely to feature
Swindon look set to include Massimo Luongo in their squad to face Brighton in the Capital One Cup.
The Australia international was rested for Saturday's 2-0 win over Crewe having suffered from a tight hamstring in the build up to kick off but the midfielder could now return to action.
However, Mark Cooper's already small squad will be stretched even more if they are unable to agree an extension to keep Derby defender Josh Lelan with the club after his initial deal came to an end after the final whistle on Saturday.
Striker Andy Williams continued his fine form since returning to action after a knee injury with his second goal in two games and he look set to start once more against the Seagulls.
New signing Joe Bennett is set to miss out for Brighton.
The on-loan Aston Villa left-back made his debut in Saturday's 2-1 win over Bolton but came off during the second half with a minor calf problem, so Adam Chicksen is likely to deputise.
Spanish striker Adrian Colunga could be involved after completing his switch from Getafe on Sunday while boss Sami Hyypia is expected to make further changes.
Goalkeeper Casper Ankergren, defender Aaron Hughes, winger Paddy McCourt and forward Chris O'Grady are among those pushing for places in the starting line-up.
