Micah Richards' knee injury will keep him out for just four weeks, according to Roberto Mancini.

The Manchester City defender was stretchered off during last week's defeat of Swansea, with initial reports suggesting he had torn a meniscus in his right knee.

A timescale of four months was put on Richards' recovery - a diagnosis repeated on the club's official website.

But at his press conference ahead of Saturday's trip to West Ham Mancini revealed the right-back could even return before the end of November.

He said: "I think maybe - it is my opinion - three or four weeks. I read three months but I don't know why. One month - maximum.

"It is not bad. Maybe in three or four weeks he can start to play. He put only two stitches in his knee. For this reason, maybe four weeks."
