Fellow defender Jermaine Grandison has an ongoing hip problem which has limited his training time as the coaching staff look at every avenue to get him back out training.
Defender Zak Whitbread, who was forced off at Doncaster, is still being monitored but Jackson has his fingers crossed that the defender will be fit to face Coventry.
Jackson also provided an injury update, admitting midfielders James Wallace and James Wesolowski are not quite ready for match action just yet as they work their way back from injury.
"Each result that you get builds confidence and I think that's been a big factor," he said.
"We spoke to the lads about the areas where it's important that we're good.
"They've taken that on board and worked really hard at it.
"A lot of the games have been battles and they're going to continue to be like that.
"The sort of football that is going to be played now is not going to be slick passing all over the place, it's about being functional and getting results.
"We needed to get back to keeping clean sheets because that then gives you the stability to go forward and maybe open up a little bit more."
And Jackson feels positive results breed confidence for the team.
Town have picked up back-to-back victories with recent wins over Rochdale and Doncaster Rovers.
"You always want to get off to a good tempo when you're at home," he said.
"It helps to get the fans behind you and get on the front foot."
Jackson believes a good start to the match at Greenhous Meadow will allow the team to get on the front foot.
"We didn't do ourselves justice in that game (at Coventry)," said Jackson.
"Coventry were the better team on the day.
"The team has changed quite a bit from then and we're a different side now.
"That's the only team where you can say we had to hold our hands up and admit that on the day they were better than us, and the Man United game.
"We're looking forward to the game and should be giving a better performance than in front of our own fans than what we did last time at Coventry."
Shrewsbury slipped to a 3-0 defeat at the Ricoh Arena early in the season, but Jackson is confident Town will be better against Tony Mowbray's side this time around.
Town host the Sky Blues in the Tuesday night Sky Bet League 1 clash at Greenhous Meadow (7.45pm kick-off) looking to make it three wins on the bounce.
Assistant manager Mike Jackson insists Shrewsbury Town are a better side now to the one which suffered defeat at Coventry City in October.
