Former British number one Tim Henman has defended the state of the courts at Wimbledon following a number of withdrawals from the tournament.

Jo-Wilfried Tsonga, Victoria Azarenka and Marin Cilic were among seven players to pull out of their second-round matches on Wednesday due to injuries suffered from slipping on the grass.

"The courts are in the same shape they always have been," Henman told BBC Sport. "It's bizarre how all these injuries are happening this year. I'm as interested as everyone else as to why there have been so many injuries as the courts are in fantastic shape."

Henman reached the semi-finals four times at Wimbledon before retiring in 2007.
