Chris Doig could make his Aldershot debut at home, while Jamie Day and Charlie Henry also come back into contention.
Centre-back Doig, who has over 200 appearances under his belt for Nottingham Forest and Northampton, arrived at the EBB Stadium on Thursday on a month-by-month non-contract deal.
On-loan left-back Day is available after being denied permission by parent club Crawley to feature in last Saturday’s FA Cup defeat at Sheffield Wednesday.
Fellow loanee Henry was also unable to feature at Hillsborough having been cup-tied due to his earlier involvement in the competition with Luton.
Striker Michael Rankine and winger Adam Smith have struggled with a virus this week but are both expected to be okay.
Shots, with just one win to their name in their last five games in all competitions, aim to get back to winning ways against a Shrewsbury side flying high in League Two.
Meanwhile, Shrewsbury boss Graham Turner faces a welcome selection dilemma.
James Wallace returns to the fray for the first time since seeing red on his debut against Dagenham & Redbridge at the start of November.
The on-loan Everton midfielder served a three-match suspension before being denied permission by his parent club to feature in last weekend’s FA Cup win over Rotherham.
Fellow loanee Aaron Wildig is also set to return to contention for a midfield berth having missed out last weekend with an ankle injury.
Both are influential performers but it remains to be seen whether Turner will change the midfield of Lionel Ainsworth, Nicky Wroe, Matthew Richards and Mark Wright, who performed against Rotherham.
Tom Bradshaw (illness) is a doubt while long-term absentees Jermaine Grandison (hamstring) and Reuben Hazell (knee) remain absent. Striker Marvin Morgan returns to the EBB Stadium for the first time since leaving over the summer.
