Reading striker Jason Roberts has been ruled out for the rest of the season with a hip injury.

The 35-year-old's last appearance for the Royals came on December 8 when they were beaten 1-0 at Southampton in the Premier League.

Roberts tweeted: "Injury Update...Rehabilitation has not been successful...seems at this point Surgery is our only option..meaning my Season is over!"

The forward joined Reading from Blackburn Rovers in January 2012.
