Pata Honda's Jonathan Rea won't make a return to competition at this weekend's Jerez World Superbike finale as his femur he broke at the Nurburgring has not yet healed enough for him to be able to ride.

Rea has been doing everything he can to try and be fit for the last round but past experience of returning too early after injury is ensuring he is erring on the side of caution.

The Castletown man will, however, try to ride at a subsequent test on Tuesday in order to assess how far down the line he is in terms of being able to turn in fast laps. Michel Fabrizio will continue to deputise in Spain.

"I only know how to ride at 100 per cent and I won't be able to do that, so coming back in competition isn't the most sensible thing to do. I have returned from injury too early in the past but I am a bit more mature now and the risk is too great," said Rea, speaking to bikesportnews.com this afternoon.

"In the test, if it isn't right I can just park it early, but there are a few things we need to try before the winter ban comes in, so every lap counts before then."
