Round-up: Middlesbrough eye forward after Hayden Hackney sale, ex-England man seals Hull switch, Sheffield United move
MIDDLESBROUGH star turn Hayden Hackney has completed his big-money move to Everton.
The fee is comprised of £16.5m up front, with potential add-ons taking it closer to £24m.
Boro have also negotiated a future sell-on clause into the deal.
The Championship Player of the Year – who was out of contract on Teesside next summer - had been the subject of intense interest from the Premier League, with the Merseysiders winning the race to secure his services.


It brings an end to a 14-year association with Boro for the Redcar-born midfielder, who has signed a five-year deal with Everton.
On the incoming front, Boro are set to sign Oxford United forward Myles Peart-Harris.
Meanwhile, England international goalkeeper Jack Butland has completed his move to Hull City for an undisclosed fee.
The 33-year-old, who has had previous spells in the top-flight with the likes of Stoke City and Crystal Palace, has penned a two-year contract, with a club option of a further year to become the Tigers’ first summer signing.


Butland, capped nine times by England, was part of the swap deal which saw Ivor Pandur make a £6million move to Ibrox.
The Bristolian, who spent loan stints at Barnsley and Leeds United early in his playing career, said: "The Premier League is the best league in the world and, personally, it’s a great opportunity to be on the biggest stage again.
"I believe it’s the level I’m capable of playing at, and I’ve done it before."
Meanwhile, Hull defender James Debayo has joined League Two side Swindon Town on a season-long loan.
Another young player heading out on loan is Sheffield United midfielder Alex Matos, who has linked up with Turkish Super Lig side Goztepe on a season-long loan deal.
Matos had a difficult first season at the Blades after joining from Chelsea last summer.
On the incoming front, United have negotiated a return for midfielder Jairo Riedewald, who has signed a one-year deal with the option of an extra year.
The 29-year-old was surprisingly released at the end of last term following a successful short-term stint. But a U-turn has seen him head back to Bramall Lane.
