Chelsea goalkeeper Emiliano Martinez was taken to hospital for "precautionary tests" after suffering a concussion during Saturday's 2-0 win at Everton. Manager Xabi Alonso confirmed it was a concussion, though further details are awaited.
The incident occurred in the 68th minute when Martinez collided with Everton defender Jarrad Branthwaite. Following an eight-minute stoppage, the Argentina international was replaced by Mike Penders, who made his Premier League debut for Chelsea.
Despite the concern for Martinez, the victory at Hill Dickinson Stadium was significant for Chelsea, as it marked their first Premier League clean sheet in nine months, ending a 23-match streak. Goals from Pedro Neto secured the win for Alonso's side.
There are now doubts regarding Martinez's fitness for Chelsea's upcoming matches against Tottenham, Manchester United, and a Carabao Cup tie at Liverpool. Premier League protocols typically require a minimum 14-day return-to-play process for concussion.
