Sussex skipper Chris Adams could return after injury for the county's two day-night National League games next week.
Adams, who been awarded a benefit year for next year, has been having intensive physiotherapy after missing the last three matches with a calf strain which he suffered as a reaction to the knee operation he had in June.
The county face Gloucestershire on Monday and Surrey two days later desperate to prove they are a better side than their record in Division Two suggests.
Last Sunday's defeat at Cheltenham was their seventh in ten games and left them rooted to the bottom of the table.
Promotion is out of the question now but Sussex have won two of their three home games and Adams says there is still a lot to play for.
He said: "I don't want us to finish bottom of the pile and if we are going to avoid that then we have got to get to string some wins together.
"We did well in the day-nighters last season and have targetted them again. I don't think we are the worst one-day side in the country and there is a determination to prove that."
Despite Sussex's dismal form, floodlit cricket at Hove remains very popular.
The county will be entertaining 320 corporate clients at both games and day-night matches against Hampshire and Lancashire later in the season are also proving popular.
