Tomas Kalas will spend a second season loan at Fulham after signing a new four-year contract with Chelsea.
The 24-year-old Czech international centre back was a key part of the Fulham side which finished sixth in the Championship last season only to be beaten in the play-off semi-finals by Reading.
Kalas is the 19th player to be loaned out by Chelsea already this summer, with many more expected to be sent out on short-term deals before the transfer window closes.

Kalas’ Chelsea team-mate Lucas Piazon also signed up to a second season-long loan with Fulham earlier this month as they look to go one better and earn promotion back to the Premier League.
‘It’s a pleasure to welcome Tomas Kalas,’ said Fulham vice chairman Tony Khan.
‘We appreciate Tomas so much after the way that he battled for us last season, demonstrating not only tremendous skill but also great heart and determination.
‘We’re very excited to have him here again as one of us as we prepare for our next battle, and what we hope will be a great season.’

Kalas signed for Chelsea from Sigma Olomouc in 2010 but has made just four appearances for the club – though one of those came as a starter as Chelsea famously halted Liverpool’s title bid at Anfield in 2014.
He has spent time on loan at Chelsea’s Dutch feeder club Vitesse Arnhem as well as at German side Cologne and with Middlesbrough and Fulham in the Championship.
Kalas, who has six caps for Czech Republic, joins the likes of Tammy Abraham, Ruben Loftus-Cheek and Kurt Zouma in being sent on loan by Chelsea this summer.
