Appleton says he has been impressed by the contributions of Nathan Delfouneso and Nouha Dicko in recent weeks and could reward one if not both with a starting place.
"I think the players coming off the bench are starting to make a mark," he told the club's official website. "We're very fortunate that substitutes have come on and scored goals at critical times for us, which has been a bonus."
Delfouneso netted the equaliser in their Boxing Day draw at Huddersfield as the Tangerines moved within four points of the play-off places.
Defender Craig Cathcart returned against the Terriers after recovering from a sickness bug and should retain his place after no further setbacks.
Neal Eardley remained on the bench in that fixture with the same problem and may have to settle for a substitute's role again.
