Great Britain's men's 4x400m squad finished fourth during this evening's Olympic relay final in London.
However, Green appeared to struggle on his leg as Team GB dropped back into fifth as Dai Greene collected the baton for the third leg.
Greene brought the team into contention before he handed over to Martyn Rooney on the anchor leg. Rooney worked hard during the last lap, but he was unable to get the team within the medals.
They eventually finished fourth in a time of 2:59.53, which is the quickest that the quartet have run all year.
Trinidad and Tobago ended in the bronze medal position, just ahead of Britain.
