Players from both sides came together in the tunnel at half-time, moments after Addicks midfielder Nicky Bailey had appeared to kick out at Norwich captain Grant Holt.

Referee Steve Tanner included the incident in his match report, with the Coca-Cola League One encounter finishing in a 2-2 draw.

An FA spokesman said: "We are aware of the incident in question and we are making enquiries accordingly.

"Depending on those enquiries, we will decide if any further action will be necessary."
