Wales attack coach Stephen Jones says George North is in a "good place" as the British and Irish Lions wing goes through return-to-play concussion protocols ahead of the Guinness Six Nations clash with England.
North was forced off during the early stages of Wales' Six Nations defeat to France in Cardiff last Saturday after suffering a heavy blow and failing a head injury assessment.
It was the sixth concussion that North - who has scored 40 tries in 94 Tests for Wales - has suffered in his career and has placed the 27-year-old's well-being under scrutiny.
"It's well documented that George has had concussion, but I think four years ago was his last one," Jones said.
"George is going through the protocols, the same as Dan (Biggar) did (before the France game).
"We've got elite medical staff looking after him, who are making sure he ticks every box. Nothing will be rushed or forced because player welfare is most important.
"George is in a good place, he's going down the correct path and he's in good spirits."
Wales' back-three options have already been reduced for the trip to Twickenham on March 7.
Wing Josh Adams has been ruled out of the tournament with an ankle problem picked up against France.
Wales have opted not to release Liam Williams to the Scarlets this weekend, even though he has not played since October because of an ankle injury.
"Liam is training with us and getting the volume into his work," Jones said. "We have to put Liam through different scenarios."
