Aston Villa captain Jack Grealish was punched around the head by a pitch invader in the early stages of their derby clash with Birmingham City at St Andrew's.

A man ran onto the field and aimed a blow at the attacking midfielder, who was jogging in the opposite direction, and seemingly caught him on the neck and jaw.

Play was halted as stewards raced on to restrain the man before they led him to a nearby police officer, while players from both teams offered embraces to the 23-year-old.

Grealish last week returned from a shin injury that had sidelined him since early December and scored in a 4-0 rout of Derby County.
