Arsenal's Brazilian forward Gabriel Jesus is set for a lengthy spell on the sidelines after suffering an anterior cruciate ligament (ACL) injury, the Premier League club said on Tuesday. Jesus, 27, left the pitch on a stretcher before the end of the first half in Arsenal's FA Cup tie with Manchester United on Sunday,

“Further to being substituted during our match with Manchester United on Sunday, Gabriel Jesus has received extensive assessments, scans and specialist reviews which have confirmed that he has sustained an injury to the anterior cruciate ligament in his left knee,” Arsenal said in a statement on Tuesday night.

Gabriel Jesus’ knee injury is “not looking good”, Arsenal manager Mikel Arteta says. The Brazil striker was taken off after 40 minutes in Arsenal’s FA Cup loss to Manchester United on Sunday.
