Derek Carr limps out of Oakland Raiders' loss at Wembley Stadium

Struggling Oakland Raiders were dealt a further blow when quarterback Derek Carr limped out of the side's defeat in London this evening with suspected knee or ankle trouble.

The Raiders lost their fourth straight game this season, with the Miami Dolphins cruising to a 38-14 victory at Wembley Stadium in a fixture that saw Carr originally author an impressive opening touchdown on his side's first drive.

The continuity wasn't there however, as the quarterback sought to stay on the pitch after being injured in a heavy scramble, but the impact evidently proved too much and he was replaced by Matt McGloin.

The Raiders are next back in action when they face the San Diego Chargers.
