Fit-again Jermaine Grandison could make his first appearance for three months for Shrewsbury but Mark Wright is facing a battle to play again this season.
Defender Grandison has been on the verge of making his comeback for some time having suffered a troublesome hip injury in mid-January, and he finally got some much-needed minutes under his belt in midweek as he played an hour for Town's reserve side.
He suffered no ill-effects and could well come into the frame against the promotion-chasing Cherries.
However, winger Wright, who has only recently overcome a long-term knee injury, suffered a hip problem in training and is currently back on the sidelines. He could, though, rejoin his team-mates next week and would then stand an outside chance of featuring before the end of the campaign.
Defenders Darren Jones (dislocated shoulder), Cameron Gayle (hamstring) and Rob Edwards (thigh) all continue to miss out.
Will Grigg is expected to return for Walsall.
Grigg, who has 19 goals to his name this term, has missed the last two matches with a hamstring injury sustained on international duty, but returned to training on Thursday and hopes to start at Glanford Park.
Centre-back Butler is only rated as 50/50 for the encounter due to a foot injury picked up in last weekend's 1-1 draw against Sheffield United.
Manager Dean Smith will be hoping his influential captain makes it, with fellow defender Andy Taylor already missing with the hamstring injury which forced him off just before the hour mark against the Blades.
Mal Benning and James Chambers, fit again after illness, are competing to replace Taylor at left-back.
