Brussels - Mercedes has revealed world championship leader Lewis Hamilton is "likely" to face penalties this weekend (August 28) at Spa.
We reported earlier that the British driver was in fact more likely to take his unscheduled sixth engine - and therefore a grid penalty - at Monza, where it is even easier to overtake.
Potential 20-place grid penalty
But Mercedes said on Wednesday (August 24) that the penalties are "likely" at Spa-Francorchamps, with confirmation "expected Thursday".
And British newspapers said Hamilton could actually move not 10 places down the grid at Spa but a full 20, as Mercedes uses the opportunity to 'double up' with two engine changes to get Hamilton through the remaining 9 races of 2016.
Rosberg to test halo device
Meanwhile, a Mercedes spokesman told us reports that Nico Rosberg will test the 'halo' device on his Mercedes in Spa practice on Friday (August 26) are correct.
It comes after Formula 1 race director Charlie Whiting said he wants every driver on the grid to test the cockpit protection in the coming months.

Whiting said: "What we are looking to do is make it clear that every driver has to try it for a whole free practice session during the course of this year.
"That would give us a proper way of going forward, to make sure that we don't get caught out by something that is very hard to change back."
Rosberg's run on Friday will be particularly interesting, with many fearing an unique corner like Eau Rouge could raise new visibility issues with the halo device.
