England captain Joe Root has challenged Jonny Bairstow to grab his recall "by the scruff of the neck" and end the Test team's revolving door policy at No 3.
Bairstow arrived in Sri Lanka as England's first-choice wicketkeeper but was ruled out of the series opener in Galle due to injury and overlooked in Kandy following Ben Foakes' fine debut with the gloves.
He will return to the XI as a specialist batsman in Colombo on Friday, live on Sky Sports, alongside returning seamer Stuart Broad, with England swapping out Sam Curran (side strain) and James Anderson (rested) as they bid for a clean sweep of wins.
The 29-year-old has also been told he will bat at first wicket down, a crucial position that has not been satisfactorily filled since the days of Jonathan Trott.
"One thing we all know about Jonny is whenever he's got a point to prove or is up against it, he generally comes out and does something pretty special," said Root.
"Hopefully we see that with Jonny this week - that determination and drive to really hammer that spot home for himself. It's an opportunity for him to try and nail that spot down and he's more than capable of doing it.
"At the minute that (keeping wicket) is not an option for him in this team and I think it's a really good opportunity for him to take his batting to another level.
"In the last couple of years he's been statistically one of the top 10 players in the world in Test cricket so it would be nice to see him really grab number three by the scruff of the neck and use it as an opportunity to start really consistently scoring big runs in this format.
"There are so many different combinations that we could go with that look extremely strong in all conditions.
"It would be, obviously, in terms of having a settled batting line-up, especially a top six - it would be ideal to get that settled down."
There are no concerns over how Ben Stokes will take his move back down to number five after precisely one innings, of 19, in the top three.
Root indicated the all-rounder's workload with the ball, which could include new-ball duties this week in the absence of Curran and Anderson, meant he had a more natural home further down the card.
"I think that's his preferred position. Long-term as well, he's going to be bowling more in the English summer," he explained.
"Although it wouldn't be impossible for him - he's a very fit guy, very able to do so - it might be a better formula to have him in the middle-order."
