I broke my thumb 5 years back, sore thing. Need to take care not to loose your pinch.
Be interested to see if Sadio plays at the weekend, can strap it up, but needs to be careful falling over. Don't think you can play with a cast or anything that hard, and not sure how something softer would offer enough support - so not sure how they manage it - though like guys have said, other players have played with healing broken bones before, so will see.
Though might be a chance to give Shaq or Studge a run.
