The Yorkshireman suffered ligament damage in his right ankle while playing football during an ODI training session warm-up and now looks unlikely to features in the Test, starting November 6.

“It’s day by day with Jonny at the minute,” England captain Joe Root told BBC Sport.

“He’s actually made good strides in the last week or so and he’s recovered a little bit quicker than we anticipated.

On Bairstow’s fitness, Root said: “We’ll have to wait and see… but we’re very fortunate to have a lot of resources in that department.

“There’s still a long way to go, we’re a long way out from the first Test and it’s a big three-match series so we’ve got to weigh that up before the first game.

“Jonny would be a big loss but we have great players to come in and rebalance the team.”

England have the option of bringing in Ben Foakes, the Surrey wicketkeeper who was added to the squad after Bairstow’s injury.

“One of the things we can take into account is the surface and the conditions – it might not necessarily be the team that played in the summer but that’s an exciting thing.

“We’re going to try and make sure we have a very balanced side that gives us the best chance of winning in these conditions.

“We’ll have to see what the surfaces are like, take everything into account, see what will get us 20 wickets and then take it from there.”
