Messages of support have been sent to Ryan Mason after the Hull midfielder suffered a fractured skull.

Mason is in a stable condition in hospital after undergoing surgery at St Mary's Hospital in London following a clash of heads with Gary Cahill during the first half of Sunday's 2-0 Premier League defeat at Chelsea.

The 25-year-old is expected to remain in hospital for the next few days.

Players from across England and Europe used Twitter to send best wishes to Mason, while the England team's account posted a message reading: "Stay strong, Ryan" alongside a picture of him earning his sole England cap to date.

The Football Association tweeted: "We'd like to send our best wishes to @RyanMason, who suffered a skull fracture while playing for @HullCity today."

Mason's first professional club, Tottenham, posted: "Everyone at the Club sends their best wishes to @RyanMason for a full and speedy recovery. Get well soon, Ryan."

Mason joined Hull in August last year after being frustrated by a lack of first-team football at Tottenham, where he came through the ranks while also spending time out on loan at Yeovil, Doncaster, Millwall, Lorient and Swindon.

Capped a number of times at youth level by England, Mason's only senior appearance to date came in a friendly against Italy in March 2015, where he set up Andros Townsend's late equaliser in a 1-1 draw.

Speaking on Match of the Day 2, former Arsenal defender Martin Keown said: "Our thoughts are with Ryan - its a terrible thing to see on a football pitch, you hope it never happens.

"Of course Gary Cahill was just innocently going for the ball. It was a sickening challenge and let's hope he gets back onto the football pitch again."

Mason's Hull team-mate Andrew Robertson tweeted: "Thoughts are with @RyanMason and his family"

Defender Cesar Azpilicueta was one of several Chelsea players to have been on the pitch at the time to send well wishes, posting: "Get well soon @RyanMason I'm sure you'll recover quickly."

Both medical teams had rushed to the scene as referee Neil Swarbrick stopped play.

Cahill quickly returned to his feet and readied himself to return to the action. He completed the game and scored Chelsea's second goal.

Mason was in hospital by then, having received treatment for around six minutes on the field before departing on a stretcher, while receiving oxygen. David Meyler replaced him.

A Hull statement on Sunday night read: "The club can confirm that Ryan Mason sustained a skull fracture in our fixture at Chelsea this afternoon.

"He was taken to St Mary's Hospital where he has undergone surgery. Ryan is in a stable condition and is expected to remain in hospital for the next few days.

"Everyone at the club would like to express their sincere thanks for the excellent and swift care given to Ryan by both the Accident and Emergency department and Neurosurgery Unit at St Mary's Hospital.

"A further update will be issued tomorrow."

Immediately after the game Hull boss Marco Silva said he was hoping the injury was not serious.

"Ryan Mason at this moment is staying in the hospital. I don't know more news about this," Silva said at the time.

"I hope nothing special, nothing serious, but at this moment the player stays in hospital."

Chelsea head coach Antonio Conte said: "Everyone at Chelsea wants to wish for him the best."
