Plymouth Argyle defender Seip signed until the end of the season this week following the end of his spell at Blackpool, where the Dutchman had been on loan since late September.
Manager Kevin Blackwell is expected to be without striker Darius Henderson (gluteal muscle) again while defender Kyle Walker also missed Monday's win over Preston due to a thigh strain.
If Walker fails to make it again Jordan Stewart is likely to continue at right-back with fellow defender Derek Geary on the opposite flank.
Midfielder Lee Williamson made a faster-than-expected recovery from a hamstring strain to step off the bench against Preston and could be pushing for a place in the starting line-up.
