The Football Association has confirmed it is investigating the crowd trouble that marred the Black Country derby and Middlesbrough's win at Millwall.
The Premier League encounter between West Bromwich Albion and Wolves was overshadowed by trouble which started when a smoke bomb was thrown from the visiting fans' section into the home crowd. The Albion supporters responded by hurling objects back at the Wolves fans, one of whom was pictured with blood streaming from his head. The FA's crowd-control officer at The Hawthorns will report back today on what he saw.
Millwall may be facing disciplinary action after ugly scenes at The Den during Boro's 3-2 win on Saturday.
The referee, Chris Sarginson, had to stop the game on two occasions and considered calling the match off after the Boro goalkeeper Jason Steele and the assistant referee were the targets of bottles and other objects thrown from the crowd.
The trouble began after the assistant allowed Scott McDonald's second-half goal to stand despite the player appearing to be in an offside position. An FA spokesman said: "We are awaiting the match officials' report and we will be seeking observations from both clubs."
