Kimi Raikkonen expects he will take to the grid at this weekend's Korean Grand Prix despite concerns about his back.
The Lotus driver suffered severe back pain last time out in Singapore and had to take pain-killing injections before racing.
That, though, didn't stop him from going from 13th to third on a track where overtaking is notoriously difficult.
Following the night race there were still concerns about whether he would opt to sit out this weekend's Korean GP in light of the pain.
Raikkonen, however, insists he will race.
"I wouldn't be here if I wouldn't be racing," he told Autosport.
"It would be a bit pointless to come here if I didn't think that I would race.
"Obviously tomorrow we'll see. Right now it's OK. It's always difficult to say until you drive, but I think it should be fine.
"Once we try it tomorrow, I'll know more. Like I said already at the last race, this wasn't the first time and I'm sure it won't be the last time.
"It's something that I've been dealing with for a long time."
The back pain is not a new issue for the Ferrari-bound driver, who suffered the injury back in 2001 in a testing accident while with Sauber.
"I've been OK every year I've been racing," he said. "Sometimes I have to deal with the pain.
"Obviously every year you get older and your system has more issues but I'm sure you can deal with these things."
