Arsenal expect to have forward Gabriel Martinelli back in training in the next few days and could have defender Gabriel Magalhaes and midfielder Thomas Partey available for the visit of Crystal Palace in the Premier League on Thursday.
However, a scan has revealed no serious damage, Arsenal club said on their website.
Fellow Brazilian Magalhaes has returned from a period in isolation after testing positive for Covid-19 and has not played for the club since before Christmas, while Partey has recovered from a thigh injury.
Partey limped out of a 2-0 loss to North London rivals Tottenham Hotspur on 6 December.
Arsenal also confirmed a new three-year contract for defender Rob Holding on Tuesday.
“He is 25 years old, so is still coming into the peak of his career, and we are delighted that he’ll be with us during these important years.”
