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.
