Warburton missed the win over France after picking up a shoulder injury, but is expected to be available for the meeting with the Azzurri. However, Ryan Jones led the side superbly in Paris, while Justin Tipuric excelled in Warburton's favoured number seven role. As a result Howley has elected to name the same side that triumphed at Stade de France.
No longer being an automatic pick for Wales does not help Warburton's Lions cause but Howley, filling in for Warren Gatland while the Kiwi is away on Lions duty, does not believe his selection for the Stadio Olimpico clash will harm the 24-year-old's chances. "Not at all," said Howley.
"Although I think that is a question for Warren Gatland, not for me.
"But there have been many players not playing international rugby who have come into a Lions selection. So it is not a given that you have to be playing international rugby to go on a Lions tour, and it's not a given you have to be captain of your national team to be captain of the Lions."
Howley did not consult Gatland before making his decision on selection for the Italy game, but did back Warburton to bounce back and find his best form.
"Any decision you make on selection, you take your time and make sure you reflect properly after the game and think out the team and the consequences of those selections.
"In my mind it was clear that to give this side the best opportunity to go and play against Italy in terms of preparation and to reward performances on the weekend I had to go with the same side.
"I have spoken to Sam and he understands that's the nature of sport.
"I am sure Sam will be an excellent captain in his career, but for this game we decided to go with same 15. The pressure on this side for Italy is the same as it was going to Paris."
