New Zealand-born Shields suffered the injury on his debut for his new side Wasps, in their 31-42 Premiership defeat by Exeter Chiefs at the Ricoh Arena on Saturday.
The 27-year-old, who was released from his contract with New Zealand Rugby in May so that he could represent England, is expected to be out for up to “three to eight weeks” after the clash with Exeter’s Stu Townsend.
Shields is set to see a specialist early next week and will know if he requires an operation after the meeting.
The flanker has earnt two caps for England under boss Eddie Jones and was expected to be a part of the squad for the autumn if fully fit.
England’s first autumn Test is against South Africa on 3 November, with Jones’ side then set to face New Zealand, Japan and Australia before December.
