The six-time MotoGP race winner badly broke his right leg in a crash during the sprint race at the Italian GP back in June.
Rins underwent surgery on the leg but recovery has been slower than expected, with the main issue now the healing of the nerves in his foot.
He has been out of action since that sprint race, missing the last five rounds.
Ahead of this weekend’s Catalan GP at Barcelona, LCR Honda has announced that Rins will continue his recovery from the sidelines as HRC rider Iker Lecuona replaces again.
Former Tech3 KTM rider Lecuona has been Rins’ stand-in since the Dutch GP at Assen, with the Honda World Superbike rider also competing in the British and Austrian GPs.
Sixteenth in the sprint race at the Austrian GP is Lecuona’s best result on the Honda so far.
A brief message from the LCR team read: "Iker Lecuona to replace Alex Rins at the Catalan GP.
"LCR Honda CASTROL rider Alex Rins is making solid progress to be on track soon. However, he’ll miss the Catalan Grand Prix and will be replaced by compatriot Iker Lecuona."
