Reading have completed the signing of Manchester United defender Tyler Blackett on a three-year contract.
The 22-year-old was handed his United debut by former manager Louis van Gaal in August 2014 against Swansea.
He spent six months on loan at Celtic last season, making eight appearances in all competitions.
Blackett becomes Reading's 11th signing of the summer following the arrival of fellow defender Liam Moore from Leicester City on Saturday.
