Chelsea defender Tomas Kalas has joined Fulham on a season-long loan, the Championship club confirmed on Thursday.
Kalas, 24, spent the whole of last season on loan at Craven Cottage, making 36 appearances as the club finished sixth and advanced to the playoffs, where they were beaten by Reading in the semifinals.
"It's a pleasure to welcome Tomas Kalas back to the Fulham Football Club," Fulham vice chairman and director of football operations Tony Khan told the club's website.
"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.
