Hodgson insists he is not concerned that he has not heard from Mascherano since trying to contact the midfielder last week.
"He doesn't need to make contact with me," said the 62-year-old.
"I've made contact with him telling him I'm looking forward to seeing him in training when he returns from his holiday but I did make the point in the voicemail that I didn't expect him to contact me.
"I just wanted him to know that I had been in touch and that I was thinking of him.
"I didn't ask him to call me back. I don't have a lot to say to him, to be honest, other than 'Welcome back'."
