More rest for Kovalainen after crash knockout

Heikki Kovalainen will spend another week recovering from a head injury sustained recently.

The Lotus driver was ordered to bed early last week after medical checks showed he suffered a heavy concussion when he crashed an Audi R8 during the Race of Champions event in Dusseldorf.

Kovalainen, who was knocked out in the crash while his girlfriend suffered minor injuries, wrote on Twitter that his recovery is "going well".

"Final scans for the head done today, no problems and just one more week resting then back to fitness training!" reported the 29-year-old Finn.
