There are reports the first test match vs india at the Gabba may be canceled, since the Australian players are in mourning. In my opinion, the match should be played as scheduled.
The best way to remember and honor Phil Hughes is by seriously looking at helmet design and other player safety issues. Canceling a match is not the solution. The players who aren’t ready to play should be given all the time they need to grieve. There will be other players that will be ready to play.
You have to put your foot in those players' shoe to realize. They are his colleague and he died playing cricket on ground, not in a motorcycle accident. The shock is too much to get over psychologically in few days to play a 5 days long test.
