Formula 2 championship leader Charles Leclerc will drive for Sauber in four upcoming FP1 sessions this year in Malaysia, USA, Mexico and Brazil.
The 19 year old Ferrari junior had previously driven in FP1 sessions for Haas in Britain, Germany, Hungary and Brazil in 2016.
He may also drive in Abu Dhabi although this is yet to be confirmed.
Leclerc is thought to be first in line for the Sauber seat next year with the team yet to confirm is it will retain Wehrlein or Ericsson and there has been growing speculation it may become a Ferrari B-team.
