The Ferrari Formula 1 team is unsure if Kimi Raikkonen will be fit to test at Silverstone this week following his British Grand Prix accident.
Raikkonen suffered bruises to his knee and ankle following a high-speed crash into the barriers on the Wellington Straight on the opening lap of the race - with an impact measured at 47-G.
After checks at Silverstone's medical centre showed that there was no serious injury to the Finn, who hobbled away from his wrecked Ferrari, his bosses are waiting to see if he will be fit enough to drive again this week.
When asked by AUTOSPORT about whether or not Raikkonen will be well enough to take part in the test, Ferrari team principal Marco Mattiacci said: "Kimi is OK.
"We checked several times and we will take a decision about the test, and what to do with the test, so we see after today.
"I want to be 100 per cent sure that he will be fine before [he does it]. But there is no major issue at the moment."
Raikkonen had been due to drive on one of the two days of Silverstone test, with development driver Pedro de la Rosa taking part on the other.
If Raikkonen cannot drive then it is possible that de la Rosa does both days, or Fernando Alonso could be drafted in instead.
Mattiacci ruled out any kind of mechanical failure for Raikkonen's accident, which appeared to be caused by him losing control of his car as he hit a bump while rejoining the track.
"I think that there was some kind of issue getting off the track, coming back and finding some bump," he said. "That was the issue."
