Robert Kubica comeback nearly impossible

One of F1's most experienced journalists has expressed grave concerns about the chances Robert Kubica will ever return to the sport.

Kubica was last racing in 2010

The highly-rated Pole has been missing from the paddock since early 2011, having been seriously injured in a pre-season rallying crash.

Until recently, there were sporadic reports about the former BMW and Renault driver's recovery, and signs his initially horrifically-damaged arm was returning to health.

But the veteran correspondent for Switzerland's Blick newspaper, Roger Benoit, has now reported that information about Kubica has stopped flowing.

"Why has the talking stopped? Because - unfortunately - a comeback is nearly impossible," he wrote.
