The LCR Honda rider broke his leg at Mugello and needed two operations to fix it.
He missed seven MotoGP rounds, as a result.
Rins returned in Japan, partaking in only Friday practice to ease back. He then finished ninth in the Indian MotoGP.

Rins, who won a MotoGP race earlier this year in Texas in Honda’s brightest moment of a drab year, has agreed to join Yamaha for 2024.
