The veteran striker has missed the Cherries' last two games and Alan Connell will keep his place in the starting line-up if Fletcher fails to prove his fitness after scoring his first goal since returning to the club a year ago in midweek.
Defender Jason Pearce is expected to return after sitting out the clash against the Glovers with a calf problem.
Reserve goalkeeper Ryan Pryce is also sidelined with a groin injury, so 17-year-old Dan Thomas will be on the bench once again.
Joe Partington and Josh McQuoid are unavailable as they are on international duty with Wales Under-21s and Northern Ireland Under-21s respectively.
Shaun Cooper (hip), Jeff Goulding (ankle) and captain Danny Hollands (knee) are also unavailable and keeper Ryan Pryce has left the club by mutual consent.
