RUSTENBURG, South Africa — England captain Rio Ferdinand injured his left knee in training on Friday and was sent to a hospital for a scan.

The center back was hurt in a collision during a training session at the Royal Bafokeng Sports Campus.

"It happened near the end," coach Fabio Capello said. "He has gone to hospital for a scan and we will have to see how things are."

In more positive news, midfielder Gareth Barry trained for the first time in public since injuring his right ankle a month ago.

The ligament damage sustained by Barry playing for Manchester City on May 5 made him uncertain for inclusion in England's 23-man World Cup squad. But he made the cut after a medical check on Tuesday.

"We have to wait day by day to see what happens with the ankle," Capello said. "The work is harder every day, stronger every day."

Goalkeeper David James, however, worked separately from the team in the complex's gym to start the session.

"David James has a little problem with the knee after a long flight," Capello said.
