Aston Villa forward Gabriel Agbonlahor has been the subject of online death threats from One Direction fans for his tackle on boyband member Louis Tomlinson.
The 26-year-old clattered into the singer during Stiliyan Petrov's charity match at Parkhead on Sunday.
The former X Factor contestant hobbled off the field and vomited on the touchline, prompting anger from his band's legion of fans.
One Twitter user @gabby_10 wrote: "This guy hurt Louis knee. I shall hurt your face. I better hear that you apologized or I will find you, and I will kill you."
Agbonlahor revealed after the match, which was organised to raise money for leukaemia treatment, that he will apologise to the singer.
