Schumi penalised for incidents

Michael Schumacher has been reprimanded by stewards for impeding the two HRT cars during second practice for the Korean Grand Prix.

The seven-time world champion, who will retire from the sport for a second time at the end of the season, was adjudged to have held up Pedro de la Rosa at turn three 48 minutes into Friday's session, before again getting in the way of the Spaniard and his team-mate Narain Karthikeyan further round the lap.

It is the latest punishment dished out to Schumacher this year. He was denied pole position in Monaco as he had to serve a five-place grid penalty for taking Bruno Senna out of the Spanish Grand Prix, and a similar incident with Jean-Eric Vergne in Singapore earned him a 10-place penalty for last weekend's Japanese Grand Prix.

This reprimand will cause particular embarrassment as HRT have consistently been the slowest team in F1 since their arrival in the sport at the start of 2010.
