Chelsea have confirmed the departures of forward Izzy Brown, defender Michael Hector and goalkeeper Jamal Blackman on loan. Brown and Hector have moved to Championship club Rotherham United and German side Eintracht Frankfurt on 12-month deals while Blackman has moved to League Two side Wycombe Wanderers until January – as the Premier League giants take their number of loan exits to 23, with over two weeks of the summer transfer window remaining.

Brown, 19, made his debut for the Blues last season against West Bromwich Albion and will have the opportunity to expand his footballing education at the New York Stadium. Millers boss Alan Stubbs told the club's website: "He is a very exciting player. He went to Chelsea for a lot of money a few years ago and they've got big aspirations for him and I think it's a feather in the club's cap the fact that Chelsea have loaned us one of their prestigious talents and one that they have really high hopes for."

Hector moved to Stamford Bridge last summer from Reading, but spent the entire campaign with the Championship club before moving to west London with two games of the campaign remaining. The 24-year-old has trained with the senior side throughout the summer and his involvement in a number of pre-season fixtures raised the possibility of him being involved in Antonio Conte's plans this season.

However, Chelsea have confirmed that despite the Jamaica international having played first-team football last term he will continue his education on the continent with Bundesliga side Eintracht – who are braced to start their fifth season back in the German top flight since winning promotion again.

The exit is followed by that of 'keeper Blackman, who has moved to third tier side Wycombe until 3 January. The 22-year-old has never made a senior appearance for Chelsea and therefore will play for a third different club in 24 months after securing his move to Adams Park on a six-month deal.

Chairboys boss Gareth Ainsworth told the club's official website: "For us to attract someone of Jamal's calibre to the club is a big coup for us, and is a result of the excellent relationship that we have with Chelsea both as a club, and me personally. He's a giant lad with massive potential to go far in the game and I'm sure he'll benefit from playing regular men's football and working under the guidance of Barry Richardson.

"Cameron was outstanding in his two games for us and we wanted to keep him here, but unfortunately we couldn't reach an agreement with Sheffield Wednesday to extend his loan. He's a great lad and we'll keep a close eye on his development as I'm sure he'll go on to have a very good career in the game.

"Jamal comes to us on a much better deal for the club and I'd like to thank Chelsea for allowing us to bring him in and trusting us with one of their young stars, who we are excited about working with and I'm sure he will learn a lot during his time here."
