Mateo Kovacic replaced Conor Gallagher in the first half of Chelsea vs Brentford due to a suspected injury. The ball was seen to canon into the 22-year-old midfielder's knee as his leg was planted in the turf.
Gallagher walked off freely after being replaced inside the opening half an hour. He seemed relatively unscathed, though it looks to be another problem added to Graham Potter's growing list.
The Cobham graduate is now one of three players at Stamford Bridge who are currently nursing knee injuries, with Wesley Fofana and Reece James out. The former hobbled off injured in the first half of Chelsea's Champions League group stage clash with AC Milan at the start of the month and is set to be out for a few weeks.
