"I am impressed by his dedication. He's had a tough time - the amount of injuries he's had would be enough to knock people away. I know the kid himself is working as hard as he can to get himself back on the field. These things happen, but at the moment everything looks pretty positive so we've just got to pray that this positivity keeps going and he has a period where he is injury-free and can show what he is capable of."
How Tuilagi would fit into a midfield equation containing four Lions in Owen Farrell, Jonathan Joseph, Ben Te'o and Elliot Daly remains to be seen. Other dilemmas loom large, too, not least whether Dylan Hartley should retain the captaincy after Jamie George started every Lions Test at hooker.
"He's like Captain Cook; if Captain Cook didn't find Australia, he wouldn't be a captain," Jones said. "Dylan knows it's not something that's he's anointed at - he's not a Lord or a Sir - it doesn't stick with him for life. It's a role that he plays, and when he plays it well he keeps the job."
Perhaps the most interesting development will be in the back row after the impressive performances of openside flankers Tom Curry and Sam Underhill in the 2-0 series win against Argentina. Both supplied plenty of turnovers at the breakdown and possess handling ability which would fit with Jones' ambition for England to evolve into a side that regularly scores off three phases or fewer.
"You listen to TV commentators and they all say you have to hang on to the ball and build phases, that's rugby 30 years ago, when I coached the Brumbies," Jones said. "You don't do that these days, it's the first three phases. And that's the ability to find the space, use the ball, keep the ball alive and be accurate in your skill work."
