Williams, who recently returned from a 10-month pelvic injury, was moved from defence into midfield for the game and looked comfortable in the role.

And the Perth-born defender/midfielder found the back of the net 10 minutes into the second-half to make it 3-2 with his side trailing.

Williams produced a fine volleyed finish from 25 yards after flicking the ball up to himself.

Boro boss Tony Mowbray said: "Taking Rhys Williams out of the back line was a massive decision because he's done fabulously well in recent games as a centre-half.

“Thankfully it paid dividends when he scored."
