West Ham defender Daniel Potts has left hospital and returned home following the head injury he suffered in his side’s 5-1 defeat at Arsenal Wednesday night.

Potts had replaced Jack Collison just after the hour mark at the Emirates Stadium, but suffered a nasty concussion following a heavy fall after an accidental aerial collision with Bacary Sagna.

The 18-year-old spent Wednesday night in hospital and underwent further scans and tests yesterday, which came back positively.

Potts has expressed his gratitude for the messages of support he has received and will undergo a period of rest before being allowed to resume light training.
