Mike Ashley has been missing from United matches since talk of the boycott began ahead of the 3-1 loss to Tottenham Hotspur.
John Carver believes fans protesting about the ownership is having a negative effect on his players.
When asked about Ashley’s presence, Carver said: “I don’t really know to be honest.
“He wasn’t there last weekend and he still got some stick didn’t he?
“It wouldn’t bother me at all if he came, but if he doesn’t come, I’m sure he will phone me beforehand, and if he does come, I’m sure he’ll come and see me before the game.
“But I really don’t know what his plans are.
“I can’t decide what Mike’s going to do, all I can decide is what we’re going to do on Sunday.”
