Matt Thornhill, Michael Townsend and Marley Watkins will all undergo late fitness tests ahead of Cheltenham`s crucial derby clash at home to fellow strugglers Hereford.
On-loan midfielder Thornhill (hamstring) and defender Townsend (groin) both missed Saturday`s 2-1 defeat at Northampton, while substitute Watkins took a knock to his ankle following his 63rd-minute introduction from the bench.
Shane Duff was an unused substitute for the second successive match following his recent return from a lengthy spell on the sidelines, and it remains to be seen whether he will be in Mark Yates` matchday 18.
The defender is still lacking crucial match fitness and the Robins have organised a behind-closed-doors friendly at Birmingham on Tuesday afternoon for him to get some action under his belt.
Seven trialists that Yates has invited to train with the club this week are also due to take part in the encounter at Blues` training ground, including former Robins loan signing Kris O`Leary and midfielder Scott Brown.
Paul Downing`s involvement for Hereford will depend on the outcome of a disciplinary hearing.
The on-loan West Brom defender was sent off in Saturday`s 5-0 drubbing at Notts County but the Bulls have appealed against the dismissal and will plead their case to the Football Association`s regulatory commission on Tuesday.
Goalkeeper Chris Adamson will definitely miss out, though, having also been sent off at Meadow Lane for bringing down Luke Rodgers in the penalty area.
The red card capped a dismal debut for the experienced goalkeeping coach and he will now serve a one-match ban, allowing regular number one Adam Bartlett an immediate return.
Manager John Trewick made five changes to the Hereford XI that went down 2-0 at home to Northampton in their previous game, but they failed to have the desired effect as County inflicted a third successive defeat.
And the Bulls boss knows another loss against Cheltenham would pull the club even further back into the relegation mix.
