Cokanasiga is not out of the picture, though, with Jones expecting the 21-year-old to play a crucial role when England travel to Japan later this year.
"I've had reasonable experience in doing this and sometimes you let them go, and sometimes you've got pull them back a bit".
Jones was then verbally abused and intimidated by Scotland supporters at a train station in Manchester on his way back from the game in Edinburgh.
"Joe's a good, young player and we're looking after him", Jones told reporters at England's training base in Bagshot, southwest of London, on Thursday.
"I don't need to fast-track him". When you're a young batsman and your first Test is against the West Indies in Perth and you bat No 3, you might not get too many runs.
"It's a great achievement but I know for him the most important thing is to win on Saturday", said Jones, who famously threw a bag of candies at Youngs when he first took over, saying he was too heavy.

"We're right at the beginning", said No 8 Hunter.
Eddie Jones says he is bringing in outside help in an attempt to solve what he sees as England's inability to cope with pressure.
"The only thing I know is that we have had a great week this week and we are absolutely excited by the prospect of us finishing well". "We have a few of them and we've got to get rid of them", Jones said.
With the focus now exclusively on the World Cup in September, Jones should be greatly concerned by how easily his team surrendered such a big lead.
England team to face Scotland: Elliot Daly, Jack Nowell, Henry Slade, Manu Tuilagi, Jonny May, Owen Farrell (captain), Ben Youngs; Ben Moon, Jamie George, Kyle Sinckler, Joe Launchbury, George Kruis, Mark Wilson, Tom Curry, Billy Vunipola. "I remember he did it a little bit with Maro and he turned out all right", he said.
"You've got to keep players' feet on the ground".
Ben Moon starts at prop in place of Ellis Genge, who also drops to the bench, in four changes in total to the starting XV.
In truth, though, England's efforts this weekend felt oddly reminiscent of the manner in which they lost their way against Warren Gatland's men in 2015.
