Rotherham United transfer news: Millers wing-back Peter Kioso leaves Championship club to join League One side Peterborough United on season-long loan

Kioso only joined the Millers on a three-year deal last summer from Luton Town, but endured a frustrating and injury-affected first campaign at the club.

The 23-year-old signed a three-year deal with the Championship newcomers in June 2022.

After suffering a groin problem in the early stages of his career in South Yorkshire, the luckless defender was then laid low by a separate ankle complaint.

He made just 13 appearances in his first season at the club.

Dublin-born Kioso - a Milton Keynes academy product - started his career at non-league side Dunstable Town before moving to Hartlepool United.

Luton brought him to Kenilworth Road in January 2020 and he was primarily brought in as a development player with potential.

He spent the 2020-21 season on loan at Bolton Wanderers and Northampton Town.
