The latest Queens Park Rangers news, views and rumours.
The Brazilian was known to suffer multiple injuries during his time at Spurs and has now been ruled out for a lengthy period once again - although Redknapp, who also worked with him at Tottenham, says it could have been a lot worse.
Indeed, far from being ruled out until the New Year, Sandro could have been out for a full year.
“It could have been a real damaging one for him and could have put him out for a year,” the QPR boss told reporters.
“Losing him until after the Christmas period is a big blow for us. He took a bad bang on his knee. We looked the video of it and it could have been even worse.”
Meanwhile, R's boss Redknapp admits his side have looked more solid without defender Rio Ferdinand but says he has 'no problems' with the centre-back.
The 67-year-old told reporters: "Him, Steven Caulker, whoever played at the back – it wasn't just Rio. They found it difficult in them early in them early games. I think we've looked more solid recently but no, I've got no problems with Rio."
