Arsenal boss Mikel Arteta had hoped to select Martin Odegaard in his starting XI for the frustrating defeat to West Ham last week - but his knock only allowed the player a brief cameo in which he scored a consolation with the last kick of the match.
Arsenal captain Odegaard was also sidelined at St James' after he failed a fitness test, as the North Londoners endured another loss at the weekend.
The Gooner understands that the 24-year-old was assessed ahead of trip to Tyneside, but the Gunners influential midfielder was ruled out.
However, the club's medical staff does not believe his injury is a serious concern - with the Norway international striving for the possibility of a return to action against Sevilla in Wednesday's Champions League clash at the Emirates.
Potential return date: November 9 vs Sevilla
