Morison worry for Shrimpers trip
Morison, who is still searching for his first goal since making a £130,000 summer switch from Stevenage, suffered a hamstring strain during Tuesday night's win over Oldham.
Morison could be out for up to a fortnight so Neil Harris, who grabbed his fourth goal of the season in midweek, or Jason Price will step in at Roots Hall.
Midfielder Nadjim Abdou is not ready to return from a hip injury, but he should be back in training next week.
The Lions are still without Zak Whitbread, who has undergone hip surgery, and fellow defenders Paul Robinson (metatarsal), Pat O'Connor (cruciate) and Danny Senda (Achilles).
