Sports club officials in Swaffham have condemned vandals who they say are putting participants’ safety at risk by smashing glass all over the Myers playing field.
Residents have been urged to be vigilant against the threat of further damage to the ground.
And police say they will also be stepping up their patrols in a bid to catch those responsible.
Officials say the latest incident was discovered by volunteers on Saturday, who then had to clear the damage themselves before the weekend’s scheduled fixtures could take place.
Swaffham Town Football Club secretary Ray Ewart said it was fortunate the damage, which they believed had been done deliberately, was spotted when it was.
He said: “The sportspeople in the town, both young and adult, are being put at risk by the mindless vandalism occurring on the Myers Playing Field.
“The field is used by several of the sporting clubs of the town and heaven help should one of our athletes become injured through this stupidity.”
A Norfolk Police spokesman confirmed the force was aware of the issue.
She added: “It is a current priority for the Swaffham Safer Neighbourhood Team to tackle the issue of criminal damage on the playing field which will include extra patrols.”
