England full-back Mike Brown returned to non-contract training today as he looks to prove his fitness in time for Sunday's game against Ireland.

The Harlequins star is following the return-to-play protocols at the moment after suffering a set-back in his recovery from a concussion injury, but forwards coach Graham Rowntree says that there's a strong chance he'll be able to play on Sunday.

"He seems normal - obviously he was groggy after the game, as we all saw," said Rowntree. "But no, he's back to normal.

"Ultimately we'll follow it day by day. But the signs are he's improving and he should complete the protocol in time and be available."
