Reading vice-captain Michael Hector is undergoing a Chelsea medical this afternoon.
The Jamaica international is set to join Chelsea in a shock £4 million deal.
Get Reading says Hector attracted interest from Crystal Palace earlier this summer.
He is currently at Chelsea's training ground finalising his switch to Stamford Bridge.
Jose Mourinho has turned his attentions to the 23-year-old after failing to land John Stones from Everton.
