Campbell, who earned three points in his first game in charge of Rovers following the sacking of Dave Penney, is sweating on the fitness of defensive duo Byron Anthony and Danny Coles, who missed the midweek win at Tranmere through injury.
The duo are struggling with ankle injuries and will be assessed on Friday before Campbell names his squad.
Midfielders Harry Pell and Gavin Williams are injury doubts after picking up knocks against Tranmere and face late fitness tests.
Some good news for the Pirates is that Jerel Ifil returns from a one-match suspension and the versatile JP Kalala is available after recovering from a toe injury.
