The 36-year-old has decided to bring an end to his career??following a season in which he struggled to hold down a regular place in a QPR side that was relegated from the Premier League.
Ferdinand was absent for the closing stages of the Premier League campaign and his wife, Rebecca??Ellison, died after a battle with cancer on May 1.
The former England defender??said: “This season I really found out that it was time to hang the boots up and get back??in the house and watch other people play the game.”
QPR wished Ferdinand all the best on Twitter saying: “All the best to @rioferdy5 following his retirement from??football.”
Ferdinand, who started his career at West Ham in 1995, became the most expensive English player when he joined United from Leeds for ??29.1m in 2002 and won 81 won caps for his country.
