Mikel Arteta is sweating over the fitness of key defender David Luiz after the Brazilian sustained a neck injury.
According to The Athletic, Luiz’s issue requires particular caution and he could face an extended period out on the sidelines.
As a result, Rob Holding is expected to remain at Arsenal rather than join Newcastle on a loan deal.
Luiz is expected to miss Arsenal’s Premier League opener against Fulham on Saturday in the early kick-off at Craven Cottage.
If the Brazilian Luiz, 33, is set for a prolonged absence it would be a major blow for Gunners boss Arteta ahead of his first full season at the Emirates.
