Sean Raggett leaves Rotherham United and more on Will Vaulks contract

The centre-half's season has been ended by the need for an ankle operation and he has returned to parent club Norwich City.

Raggett, brought in from Carrow Road in the summer, suffered a series of injuries during his time at AESSEAL New York Stadium and made only six starts and one substitute appearance in the Championship for the Millers.

"He was unlucky. He kept getting injured so his time with us was stop-start," said manager Paul Warne.

"It's a pity for him. I still think he's ideal for us. He's a threat on set-pieces and he's a proper old-school centre-half. There aren't many of those around anymore. He's one tough character."

Raggett's final outing in a Rotherham shirt came against Leeds United on January 26. He made a return to light training until it was decided surgery was required.

Meanwhile, Warne says he will attempt to tie Will Vaulks to a longer Millers deal in the summer after the club this week exercised their option to extend the midfielder's exisiting contract by 12 months to 2020.

"I've been trying to convince him to sign a new deal but we can't agree at the moment," the boss said.

"He's done really well. I sincerely hope he gets a Welsh international call-up pretty soon. He dedicates his life to playing football and he's a good kid so obviously I want him to stay longer than another year.

"While ever I am here, I will always want him to stay. I'll do everything I can to get him to sign a longer deal. We'll talk again in the summer. Now the option is sorted, we have a bigger window to try to sort it.

"We both knew that the option to extend his contract would be taken up. To avoid any ambiguity, we thought we would do it and announce it now. He's happy with that."
