Izzy Brown who has made only one first team appearance for Chelsea, will now spend the season at Championship club Rotherham.
He spent last season on loan over with Dutch club Vitesse Arnhem.
A Chelsea statement read: “Izzy Brown has today signed for Rotherham United on loan until the end of the season.
“The attacker captained our Under-19s to UEFA Youth League glory in April 2015 and a month later made his first team debut against West Brom. He has also won the FA Youth Cup twice at Chelsea, in 2014 and 2015.
“Brown, an England Under-19 regular and a European Championship winner with his country at Under-17 level, spent last term on loan at Vitesse Arnhem.
“He will now continue his development with the Championship side managed by Alan Stubbs.”
The 19-year-old forward joined The Blues back in 2013 from West Brom just after making his senior debut for the Baggies.
