LONDON: America's Wimbledon finalist Andy Roddick withdrew from the season ending ATP Masters tournament on Tuesday with him explaining that he had not recovered from a knee injury.

The 27-year-old has been suffering from the knee ailment since the Shanghai Masters in late October.

He will be replaced in the eight man draw by Sweden's Robin Soderling while Frenchman Jo-Wilfried Tsonga is first reserve for the tournament which begins here on Sunday.

The draw for the two groups is on Wednesday.
