Burnley's Lyle Foster sidelined indefinitely over mental health concerns
The South African has scored three goals for Burnley this season in eight appearances.
"Recently, Lyle let us know that he continues to live with issues around his mental well-being and has reached out for help," Burnley said on X, formerly known as Twitter.
"He is currently in the care of specialists - giving him the support and care he needs to help him back to full health."
Foster has earned 10 caps for the South African national team as well.
"We ask for your understanding and respect for Lyle's privacy around this matter and will not be making any more comment until further notice," Burnley added.
