Chelsea defender Carl Magnay has suffered a bad knee injury.

The defender's knee gave way shortly into the second half of their friendly with Charlton Athletic with nobody around him, and the prognosis is not good.

Coach Steve Holland was understandably concerned following the 3-2 win over the Addicks, in which Jacob Mellis scored our first and Fabio Borini notched twice.

"Carl's injury is a bit of a disaster I'm afraid," Holland told chelseafc.com. "We are still awaiting results of the scans but the early assessment is that he has damaged his anterior cruciate ligament, and that there is damage to the medial collateral ligament, and an issue with a cracked kneecap also, so that's a really nasty injury."
