The England international has been out of action since March 17.
The 32-year-old was expected to be ready for the new season but suffered a thigh injury.
He told MUTV: “I probably did a bit too much, I was a bit over-excited getting back and I just felt my thigh a little bit. It’s frustrating and has added a bit of extra time (to the recovery).
“Hopefully in the next week or two I’ll be back and I hope to be playing games in the next couple of weeks definitely.
“Because I’ve been out for such a long time I think the Everton game is going to be too soon, I think it will probably be after that.”
