Modric still short of fitness
The 24-year-old former Dinamo Zagreb star suffered a broken leg in Spurs' 2-1 win against Birmingham City at the end of August, ruling him out for at least six weeks.
Redknapp admitted that he had hoped the playmaker would be nearing a return by now.
However, he confessed that the reality is that he is still a long way from making a full recovery.
"He is still quite a way away. The leg is very tender, and he is very hesitant on his leg still," he said.
"So he is still a long way away really. I was hopeful he'd be close after the international break but he hasn't recovered really. He's not happy with it at the moment.
"I wouldn't like to put a time on it. We started him trying to jog last Friday but he's very tender with it."
