F1 news briefs: Tuesday

— Renault and Mercedes will be without their regular reserve drivers at Spa-Francorchamps this weekend.

Nick Heidfeld has become Pirelli’s permanent tyre tester, while Renault regular Ho-Pin Tung is recovering from a back injury sustained recently during the GP2 race in Hungary.

The Chinese may be fit enough to return to action at Monza in three weeks.

— The FIA has moved to detract F1 drivers from cutting the Les Combes chicane during this weekend’s Belgian grand prix. Three bumps, similar to the ones in Barcelona, Valencia and Monza, have been placed across the run-off area.

— Force India reserve driver Paul di Resta will not be driving the VJM03 during Friday morning practice at Spa.

"We’ve got some work to do on the new blown floor and the low downforce package so it’s natural we need to give the race drivers the additional time," said the Scot.

He will be back in action at Monza.
