London - Lock Courtney Lawes re-joined the England squad in Portugal on Monday evening after receiving treatment back home for a back injury.
However, England coach Eddie Jones told England Rugbyâs official website that the Northampton Saints forward remains a doubt for Saturdayâs Test against South Africa at Twickenham.
Lawes returned for specialist treatment on a pre-existing back injury at the weekend, but following his return to camp on Monday it is hoped he will return to light training on Tuesday.
âHe came in injured from the (Northampton) game. We did a walk through on Wednesday and he realised it wasnât right so our medical team got onto it straight away. It was investigated here but it required treatment so he went home.
âAt the moment is seems like itâs had the required effect and we will wait and see how he comes in tonight,â Jones said.
Jones is already without experienced lock forward Joe Launchbury and admits the loss of Lawes would be a blow for the side.
Jones will name his side on Thursday.
