Hull are set to unveil USA striker Jozy Altidore and Stoke midfielder Seyi Olofinjana as their first major summer signings on Thursday.
The club have not named the pair but a deal for Olofinjana was all but confirmed by comments from Stoke manager Tony Pulis earlier today.
Altidore, having been linked with Hull in recent days, has also indicated he, too, is likely to be signing with his latest comments on Twitter.
"First match is against Chelsea, subject to a work permit *wink* *wink*," the 19-year-old wrote.
The Tigers begin their Barclays Premier League campaign at Stamford Bridge on August 15.
Altidore, who is currently with Spanish club Villarreal after catching the eye for New York Red Bulls, is highly rated in the US and shone in the recent Confederations Cup.
The details of any move are unknown but, if a permanent deal has been agreed, the £5million club record fee paid for Jimmy Bullard could be broken.
Hull considered a move for Nigeria international Olofinjana last summer but the 29-year-old instead joined Stoke from Wolves.
He made an early impression at the Britannia Stadium, starting their first 13 Barclays Premier League games, but then slipped down the pecking order.
That persuaded him to seek a move and, after speaking to Monaco earlier this summer, he is thought to have negotiated a three-year contract at Hull.
Pulis told the Stoke Sentinel: "He goes to Hull with our very best wishes.
"Although we will be giving him to another club that will be fighting for their lives again, I don't think you can cut across the career and livelihood of a good professional such as Seyi.
"If it's a good move for the kid, then you have to be fair and honest to them, especially if they have been really good in their time with the club and not been any problem whatsoever.
"Seyi really is one of the nicest players I've come across in football, a real gentleman, so he goes with our best wishes."
