Former West Ham goalkeeper Shaka Hislop is conscious and recovering after collapsing on air before Sunday's friendly between Real Madrid and AC Milan in California.
The 54-year-old was working as an analyst for US broadcaster ESPN.
He stumbled and fell to the ground face forwards during a pre-match pitch-side interview at the Rose Bowl in Pasadena.
Dan Thomas, presenting alongside Hislop, called for assistance as the channel cut for a commercial break.
Temperatures in California on Sunday were reported to be about 30C, but it is unclear if heat was a factor in Hislop's collapse.
