Giedo van der Garde could sit out as many as four sessions as Caterham run reserve drivers in Friday practices.
The 27-year-old rookie joined Caterham at the start of this season, securing a best result of P15 in the Malaysian Grand Prix.
However, Van der Garde's preparations will take a knock in Bahrain and at three other events as he hands his car over to either Alexander Rossi or Ma Qing Hua.
The Dutchman, though, doesn't begrudge the reserve drivers as it was a Friday role that helped him secure his Caterham drive.
"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. I had that same role with the team last year and because of the work I did then, I earned this race seat."
