The Black Cats confirmed earlier this week that the 48-year-old's tenure had been extended to include the visit of the reigning Barclays Premier League champions to the Stadium of Light.
Ball has put himself forward as a candidate for the permanent role, with owner Ellis Short still assessing his options after holding talks with a series of potential replacements for Paolo Di Canio.
While he waits, the club's senior professional development coach is happy to hold the fort with the break for international matches following this weekend's fixture.
Asked if he was any clearer about how long he might remain at the helm, Ball confirmed there had been talks with the board, with more planned.
"We spoke to them earlier in the week and they said about taking Saturday's game and then we would speak after, and I was quite happy to do that," he said.
"Yes, some people might say, 'You are better off getting it sorted out', but ultimately, they have got a little window now."
Ball's two games in charge to date have seen him guide the club to a 2-0 Capital One Cup victory over Peterborough, and Sunday's more sobering 3-1 league defeat by Liverpool on Wearside.
That left the Black Cats still marooned at the foot of the table with just a single point from the 18 they have contested to date and facing another tough assignment this weekend.
However, Ball saw enough in a much-improved display against the Merseysiders to give him cause for optimism despite the severe challenge posed by his side's forthcoming mission.
