Hallam Amos who was early picked for the Team Wales Sevens squad for the Gold Coast Commonwealth Games next month is also available for selection for Friday's game following Wales duty during the Championship.
Welcoming back Hill who started all five games for Wales - only one of three to do so - and Dee who made his first Test start as well as four appearances as a replacement Jackman was quick to recognise their contribution to the team.
“It’s massive for us,” said head coach Bernard Jackman. “Both Cory and Elliot had big campaigns.
“Cory as a leader and has been so important to us, while being part of the Welsh leadership group and the fact he has played so many minutes in the competition will add to that.
“Elliot got capped in November but to become an important part of the Six Nations campaign was huge.
“We are very excited to get them back in and playing for us on Friday, we will give them some time off next week but it’s important for us that they keep going and they wanted to play.
“They have been in touch throughout the Six Nations and are keen to get back and help us get a win.”
Back row forward Ollie Griffiths (thigh) and scrum-half Sarel Pretorius (illness) are set to return against the Cheetahs after being late withdrawals from the team to face the Kings in Port Elizabeth.
Unfortunately the Dragons will be forced into at least two changes after Wales tighthead Leon Brown (toe) and centre Jack Dixon (elbow) suffered season-ending injuries at Nelson Mandela Bay Stadium.
“We think Leon is one of the most exciting tightheads in the world and he was great for us at the start of the season and we were so happy for him to get capped,” said Jackman.
“Unfortunately he got a concussion that took a long time to clear up then a foot injury against the Kings.
“It’s disappointing but Lloyd Fairbrother, Nicky Thomas and Dan Suter are all fit so there’s no crisis at tighthead – and Lloyd has been having a really big season.”
