Injured Federer battles through
Tennis:Roger Federer shook off a back injury to beat Xavier Malisse 7-6 6-1 4-6 6-3 and reach the Wimbledon quarter-finals. The six-times champion left Centre Court after the seventh game of the first set for treatment and returned eight minutes later before dropping his serve to trail 5-6.
The third seed broke back immediately, however, and roared through the tie-break 7-1 before dominating the second set.
The 31-year-old Malisse, world number 75, broke the Swiss early in the third set and with Federer's movement clearly
restricted the underdog pulled a set back.
Federer received more off-court treatment and dropped his serve again at the start of the fourth set but Malisse's game suddenly fell apart and the 16-times grand slam champion wrapped up victory with an ace.
"I felt my back going at the beginning of first set and played for three or four games," Federer told reporters. "Maybe it was the two days off and the cold wind today but I managed to pull through in the end."
Andy Murray continues his quest to give Britain its first male grand slam champion since 1936 byt taking on big-serving Croat Marin Cilic on Court One.
