Injury puts Coulthard out of test

Coulthard aims to be fit for the final day of the test

David Coulthard has pulled out of Red Bull's test session in Barcelona because of a neck injury.

The Scot, 36, tweaked a neck muscle on the first day of the final pre-season test and will be replaced in Tuesday's run by Toro Rosso's Sebastian Vettel.

Coulthard will undergo treatment in the hope he will be fit for the final day.

The team said Coulthard's injury is not serious but he does not want to aggravate it ahead of the season opener in Melbourne on 16 March.

Coulthard, who is entering his 15th season in Formula One, only managed 25 laps during Monday's test at the Circuit de Catalunya.

Testing was affected by wet weather in the morning session but the car also struggled with technical problems.

Coulthard's team-mate Mark Webber completed 71 laps with a best time of one minute 23.115 seconds, just over a second short of pacemaker McLaren's Lewis Hamilton.

Vettel is available to cover for Coulthard on Tuesday because Toro Rosso, Red Bull's sister team, are only running one new car in Barcelona.

Lewis Hamilton set the pace for the second day running in Barcelona, posting the fastest time of one minute 21.234 seconds.

McLaren team-mate Heikki Kovalainen was 0.2secs adrift with Ferrari's world champion Kimi Raikkonen almost 0.5secs back.

It was another bad day for Renault, however, with double world champion Fernando Alonso down in 13th while team-mate Nelson Piquet was 18th.
