Chelsea goalkeeper Thibaut Courtois has been cleared to play on after undergoing precautionary tests following the head injury he sustained during Sunday’s 2-0 Premier League win over Arsenal.

The Belgian played on after requiring treatment for a head knock following a first-half collision with Arsenal forward Alexis Sanchez, before being replaced after further treatment and departing Stamford Bridge for precautionary scans in hospital.

A Chelsea statement read: “Chelsea Football Club can confirm Thibaut Courtois went to hospital for precautionary tests on a head injury.

“Those tests came back all clear. Thibaut was treated for a minor cut to his ear and was released from hospital. He is expected to report for international duty later this week.”

Headway, the brain injury charity, has questioned the application of the Premier League’s regulations following the decision to allow Courtois to play on.
