Championship side Peterborough United have signed Leicester City centre-back Josh Knight for a "substantial fee" on a three-year contract.
The 23-year-old played 34 times in two previous loan spells with the club in the 2018-19 and 2019-20 campaigns.
Knight, who first joined Leicester aged eight, spent last season on loan with Wycombe, making 39 appearances.
"He ticks every box and the most pleasing thing is that it's a permanent deal," said Posh boss Darren Ferguson.
"The boy is delighted to be back, the lads are also delighted he is back I have to say and another bonus is that he already knows how I want to play."
Knight made his only senior appearance for the Foxes in an EFL Cup tie against Sheffield United in 2017.
