The former England Under-18 captain responded to his call-up in some style by grabbing two tries in a 36-7 victory over Esher Rugby at frozen Sixways.
The 18-year-old will now miss the league game at Doncaster Knights as he jets out with Worcester team-mate Andy Short this week for a training camp with England Under-20s in Portugal.
However, he departs will Hill insisting the all-action back row is a star in the making who along with Short and scrum half Ollie Frost will form the future of the club.
"On the back of that performance, Matt has got a good future here," said Hill. "He is an 18-year-old who plays way above his years and I am delighted with him.
"He will be away with England now for a spell but when he is with us we will try and keep him involved as much as possible because he is an outstanding young talent.
"With players like Matt, Ollie Frost and Andy Short, we have three players who are the future of Worcester Warriors.
"They are the future because of their attitude, hard work and because they are so dedicated. They are all totally committed and when they go out on the pitch they play their hearts out. That is exactly what you want from the key young players coming through the club.
"You would play with those next to you every single week because you know they will give you absolutely everything and full commitment. They have a great attitude.
"Matt can play in all three positions across the back row, he is very much like Pat Sanderson in that regard, but we will look to groom him as a seven," added Hill.
