Berlin, Germany - McLaren reserve driver Kevin Magnussen will be absent from this weekend's (September 19-20) Singapore F1 GP paddock after breaking his hand while cycling.
Magnussen tweeted on Tuesday (September 15): "Broke my hand after falling off my bicycle. Better stick to four wheels."
He included a photograph of his bandaged left hand.
Hoping to find a 2016 seat
Magnussen raced for McLaren in 2014 alongside Jenson Button and was drafted for the 2015 season-opener when Fernando Alonso was ruled out with concussion from a crash in testing.

Magnussen is currently looking for a drive for 2016, with McLaren's racing director Eric Boullier saying recently that the team hoped to help both him and Belgian GP2 leader Stoffel Vandoorne find a seat somewhere.
Boullier said: "McLaren have only two cars, only two race seats and we have two world champions and we do intend to keep them so far.

"Kevin and Stoffel are very good. Both of them we expect to race in F1 and if we can't accommodate them we will do our best to make sure they can race next year (2016)."
Magnussen, who finished second on his F1 debut at the 2014 Australian GP, has also been linked to the new U.S-owned and Ferrari-powered Haas team which is due to enter the sport in 2016.
McLaren have had a nightmare 2015, the sport's second most successful team struggling among the backmarkers in the first season of their new partnership with Honda. They are currently ninth of 10 teams.
