Boro slipped to a fifth defeat in six matches when they went down 1-0 at home to Leyton Orient on Saturday.
They are still without defender Jon Ashton, who has undergone surgery on his Achilles, while striker Patrick Agyemang has been carrying a hamstring injury.
But Smith has plenty of options, with seven-goal midfielder Robin Shroot back on the bench at the weekend following a spell out.
Spanish forward Dani Lopez came on as a substitute for his first appearance since returning from a loan spell at Aldershot where he scored six goals in 11 games, so he is also pushing for a place in the starting line-up.
