MK Dons have signed Sunderland striker Will Grigg on loan and Walsall defender Zak Jules for an undisclosed fee.

Grigg was the Dons’ leading goalscorer in the 2014-15 season as the club won promotion to the Sky Bet Championship.

The 29-year-old netted 22 times in just 50 appearances while in Milton Keynes and is looking to pick up where he left off.

The Northern Ireland international told the club’s website: “I’m so pleased to be back.

“I’m grateful to everyone at the club for getting this one over the line and I can’t wait to get going again.

“I absolutely loved my time here before. I had such a successful spell, scoring goals and winning promotion and, as soon as I knew about the interest, it was something I wanted to push through.”

Jules, 23, has made 66 professional league appearances for the likes of Motherwell, Port Vale, Shrewsbury and, most recently, the Saddlers.

He said: “I’m buzzing and glad to get it over the line. It’s been a hectic day but I’m happy to finally be an MK Dons player.

“As soon as I heard about it, it was a no-brainer for me. This is a great opportunity for me at a great club and, of course, in a team that plays the way that way we do.”
