Hill has been delighted by the recent progress made by the duo who are now taking part in some training sessions at Sixways.
"Chris Pennell is looking very good. I would play him tomorrow if it was me - but the medical team tell me I can't," smiled Hill.
"We are still looking at the game against the Army here on Wednesday, February 23 as his first game back along with Matt Mullan.
"We probably won't push Chris before that, but he is beginning to train in the skills sessions and is looking strong. He has been on the weights and he is has twice the size shoulders he had before. Although he had this horrific ankle injury he has been able to do a lot of work in the gym and is coming back twice the size.
"Before Chris and Matt come back they will be the fittest two players in the club," revealed Hill. "They have done nothing but strength and conditioning since August so in terms of running fitness and strength they are very good.
"Both are mentally strong and confident in their rehabilitation. We will watch them when they come back, but I would expect them to have full confidence in around three to four games. They will be spot on and two very good additions to the squad.
"They are training with us with Chris doing skill work and Matt Mullan working with Phil Davies and the forwards work indoors.
"They now have two months working practically with us and they will be absolutely right when they return."
