Not really, a professional sports club should be able to reseed & have a pitch ready in 6 weeks. That of course assumes they use the correct seed blend. Sheffield would be 7 weeks after we last played & Fev 8 weeks.
Given that AFC's first league game of the season at home is 30th July, I suspect this is more about that than the pitch not being ready. Glad we will be playing in black for those 2 games, we should now "Bin the Blue".
