The 13-goal striker, who recently signed a new contract at The Den, was ruled out of last weekend's 1-0 win over Doncaster with a muscle strain.
But he returned to training on Thursday morning and manager Kenny Jackett will make a late call on whether to include the Wales international.
Norwich loanee Jens Berthel Askou returns from a three-match ban after he was sent off on his Lions debut against Leicester last month.
Fellow defenders Tony Craig (back) and Darren Ward (ankle) are still sidelined but could be back next week along with January signing Hameur Bouazza, who is recovering from a knee injury.
Striker Josh McQuoid is still a fortnight away with an ankle problem.
