Brett Cullinane has sore ribs following the 45-5 win over Old Boys and Tim Sawyer is still nursing a sore knee.
But the biggest problem is in the backs where Tommy Barff is back in training but still has a very sore shoulder. Andrew Hare has a stomach bug and, while he turned up to watch Thursday's training session, he made sure he stayed away from the rest of the squad.
With Peter Hodgson away on holiday in Australia it looks like the talented duo of fly half Paul Moss and full back/winger Martin Todd could play some part on Saturday.
The good news is that Ed Britton has returned to Durham to get ready for Uni and he is training. The athletic flanker made a big difference when he arrived along with Tom Rance last season.
It'll be a squad of 22 to face Tech - quite who will be in that squad probably won't be known until lunchtime on Saturday.
