Sky Blues manager Mark Robins is hoping to head to Sunderland with both Martyn Waghorn and Kasey Palmer ready for action.
The Sky Blues duo both missed the final pre-season fixture of the summer, against Portsmouth.
The club were also without captain Liam Kelly, who is set to remain sidelined for a number of months.
However, both Palmer and Waghorn remain in contention to feature against The Black Cats on the opening day with Palmer having already made his return to the training pitch.
“Kasey Palmer is back now, so we’re alright on that front and long may that continue," said the manager.
“Martyn Waghorn has been out a few days. He had a calf issue, but thankfully there was no tear.
“He’s a senior professional that knows his body and it wasn’t right for him to continue to play.
"He’s had a few days out and some treatment and, hopefully, he’ll be cleared to train before Sunday.”
While the club will remain without Kelly on Sunday, the rest of Robins' squad is available to feature.
However, with the earlier start than usual due to the newly-implemented winter break, the City manager anticipates a rigorous season but one to look forward to.
“Pre-season has been really good on that perspective, apart from Kelly;'injury," he continued.
"Like I say, it’s a long season with a lot of games coming thick and fast and we always say it but it’s totally different this year.
“The supporters will find that it’s tough going, but hopefully we can give everyone the same level of enjoyment they’ve had over the past five years.”
