A month seems a very short time for an injury to be honest. How much of an update can you expect.
24hr a day sports news has a lot to answer for.
Depends what kind of injury, though.
Weekly updates on Gomes, for example, would be pointless. But if Bernard was supposed to be out for 6 weeks (I think that's what it was) and it happened a few weeks ago, then it's not unreasonable to expect more regular updates as his estimated return approaches.
It only really becomes a problem when there's a chance they may make the bench one weekend but then don't end up playing for another 2 months.
