The Welshman told the Journal: "I don't want to push myself just for the sake of returning earlier than expected.
"There's no point trying to break a record if there's a risk that something might go wrong.
"I'd be foolish to rush back and, although I'm on course to make a comeback by the end of the month, I'll be quite happy to wait another week if that's what's needed.
"Everything is going well and I'm running at about 65 per cent.
"I'll just aim to be back out there as soon as possible and make sure that when I do come back, I won't let anyone down.
"Hopefully that will be at White Hart Lane at the end of the month, and if I keep progressing at this rate, then there's every chance that will happen.
"So far everything is ahead of schedule, but I know that you can reach a plateau with certain injuries and I'm prepared for that happening here. I might have to slow down a bit."
