Boro head coach Aitor Karanka has confirmed that the bobble that led to QPR's second goal on Saturday was caused by a bottle top on the pitch.

In the 4th minute of of injury time, QPR goalkeeper Robert Green booted the goal-kick down field - much to the annoyance of his own bench, who wanted him to ‘kill the game’ - and Jozsef Varga headed it back to Kenneth Omeruo.

Omeruo passed back to Boro keeper Dimi Konstantopoulos who, attempting to hit a first-time long clearance forward, missed the ball, which bounced off the bottle top, and allowed sub Bobby Zamora to nip in and walk the ball into the vacant net.

QPR rubbed salt in the hosts’ wounds by grabbing a third when Zamora headed a high ball into Morrison, who drove across the edge of the box before lashing a stunning shot past Konstantopoulos.

Boro defender George Friend described the incident as " a total freak ".
