Williams has dropped its appeal against Felipe Massa's exclusion from the final classification of the Brazilian Grand Prix for a tyre temperature and pressure irregularity.

The team confirmed on Sunday at Interlagos it would appeal against the FIA's decision but have now withdrawn its appeal having had three days to make a decision.

The FIA decided Williams was in breach of technical and sporting regulations in Formula 1 and subsequently disqualified the Brazilian driver post-race after he finished in eighth place.

It was reported that Massa's right rear tyre was at 137oC, 27oC above the maximum tread temperature which the team disputed at the time.

Williams has confirmed it still doesn't agree with the decision by the FIA and feels it has the evidence to disprove the penalty but it has opted not to appeal because the team feels a reversed decision will not change Williams' position in the F1 Constructors' championship and would be an unwanted additional cost.

With one race to go in the 2015 F1 championship, Williams has secured itself third place in the teams' standings regardless of results in Abu Dhabi next week, while Massa's chances of catching team-mate Valtteri Bottas and Ferrari's Kimi Raikkonen also looks unlikely, with an 19 and 18 point deficit.
