Caterham reserve driver Alexander Rossi is set to take part in four practice sessions for the team this season.
The 21 year old American joined Caterham at the start of 2012 and took part in practice during last year's Spanish Grand Prix.
Caterham confirmed at the start of the year that Rossi would take part in selected sessions and regular driver Giedo van der Garde has revealed that Rossi will take part in at least four sessions, the first in Bahrain.
"As it stands I will lose four Friday sessions," Van der Garde told GPUpdate.net.
"The first one I won’t be driving is Bahrain. I would have rather be driving these sessions myself and get as much track time as possible, but this is in the contract and I’m sure it will be good experience for these guys," he added.
Rossi's participation in Barcelona practice last season meant he became the first American to take part in an official F1 event since Scott Speed in 2007.
Rossi also drove for Caterham in last year's young driver test. He finished in eleventh place in Formula Renault 3.5 last season.
Caterham's other reserve driver, GP2 racer Ma Qing Hua, is set to take part in practice for the Chinese Grand Prix. Ma will replace Frenchman Charles Pic for the opening ninety minute session.
