Although the severity of Walker's injury remains uncertain, initial reports suggest that it may not be too serious. He has withdrawn from England's squad for their match against Belgium, but Manchester City is hopeful he'll be fit to face Arsenal at the Etihad Stadium.
The issue appears to be a tight hamstring rather than a strain, and Walker's progress will be closely monitored over the coming days. He joins Jack Grealish, Ederson, and Kevin De Bruyne in the City treatment room, with Grealish aiming to recover from a groin injury in time for the Arsenal clash.
However, Ederson and De Bruyne are doubtful for the match and will be assessed closer to kickoff. Ederson could potentially be out for up to four weeks with a muscle injury sustained earlier, while De Bruyne's groin problem led to his omission from the Belgium squad.
With a busy schedule ahead, including key Premier League fixtures and a Champions League quarter-final tie against Real Madrid, Manchester City is eager to have as many players available as possible. Currently sitting third in the Premier League, they're chasing both Liverpool and Arsenal at the top of the table with 10 games remaining in the season.
