McCall gives more details in his post match - didn't want to use it as an excuse if they lost, which is fair enough.
Sounds like they have been struggling with a number of injuries the last couple of weeks, and at least Kerr and ZFA were not fully fit, while 7 or 8 were being iced after the game. And McManus has been dealing with personal issues that have been a distraction.
Also seems like Vigurs is injured too, but he didn't say if it would hamper his return after suspension.
