The pair missed Wednesday's draw with St Mirren after being sent off against Kilmarnock but will be reinstated to Peter Houston's side.
United also have a doubt over Morgaro Gomis, who picked up a knock in training on Friday, but they are optimistic he will make it.
Darren Dods (knee), Scott Severin (ankle), Danny Swanson (back) and Paul Dixon (calf) are all out.
