Striker Famara Diedhiou returns to the Bristol City squad ahead of their Sky Bet Championship clash with Nottingham Forest at Ashton Gate.
Diedhiou is available after serving a three-match ban following his straight red card in the 2-1 victory at home to Charlton on October 23, in which he scored the equalising goal.
Defensive midfielder Korey Smith is close to a comeback after seven months out recovering from a broken bone in his foot and ligament damage, while full-back Jack Hunt is poised to return from a hamstring problem.
Dawson has been sidelined with a calf injury since the end of September but is set to return to the squad.
Carl Jenkinson is also close to a comeback following an ankle injury which has kept him out since the end of August.
