Sunderland boss Jack Ross has been busy in the transfer window so far this summer.
Sunderland kick off their season against Charlton Athletic on Saturday, after what has been a busy week of transfer action for them.
Sunderland have brought in Luke O’Nien, Jack Baldwin and Sinclair in recent times.
And Ross is considering starting both O’Nien and Baldwin at the weekend.
He said: “Fitness-wise, they [Baldwin and O’Nien] are OK. They have come from other clubs so they have been involved in pre-season, which is different to a free agent who might be catching up fitness-wise.
“The exception is Jerome who is still playing catch-up because he was really on the periphery at Watford, but the other two lads would have been part of what their clubs were trying to do for the start of the season.”
Baldwin could step into Sunderland’s defence, and play alongside Glenn Loovens.
O’Nien, meanwhile, looks likely to add energy to Sunderland’s midfield options.
The Black Cats go into this season under pressure, as the bookies’ favourites to win League One.
Sunderland are the biggest team in the third tier, but Charlton looks to be a tough test to start off with, as the Addicks also are among the leading contenders for promotion.
