After speaking to Nigel Adkins, Watts has reported today that Pavel Pogrebnyak and Jamie Mackie are both expected to miss out on Saturday's Championship game with Norwich.
They join a seemingly never ending rotating cast in the treatment room which also includes Jem Karacan, Danny Guthrie, Hope Akpan and Craig Tanner.
There's still no confirmed timetable for Karacan or Guthrie, while Akpan and Tanner are both expected to miss large chunks of the rest of the campaign.
On the positive side of things, defender Anton Ferdinand has been cleared to make a return - welcome news after Alex Pearce's suspension was confirmed.
We'll have more news from the training ground with Charles a little later this afternoon on this week's Tilehurst End Podcast Extra.
