Shrimpers wait on duo
Phil Brown will run the rule over Ryan Leonard and Luke Prosser as he goes in search of his first win in charge at the sixth attempt.
Midfielder Leonard required stitches to a head wound sustained late on in Saturday's goalless draw against Bristol Rovers but is eager to play at the EBB Stadium.
He stands a greater chance than defender Prosser, who missed out altogether and is still struggling with a little bit of back pain.
Goalkeeper Paul Smith is set to sit out with a virus while Tamika Mkandawire plays the final match of his current loan spell from Millwall.
Boss Brown made five changes against Rovers at the weekend - recalling Leonard, Daniel Bentley, Anthony Straker, Matthew Lund and Freddy Eastwood - and it remains to be seen how he will line-up against bottom club Aldershot with just three matches remaining and the Shrimpers destined for a mid-table finish.
