A few seasons ago the League gave all teams a set of substitute bibs to help identify them in any technical area or dug out.
Following the meetings with Clubs where this issue was raised the League MC agreed to purchase and replace those bibs.
ProKit will be sending them out to you shortly.
New Clubs in the League have already been given sets for their teams at the start of the season.
Clubs not using the bibs are likely to be fined.
It was the Clubs that expressed the wish that standards on match day are improved and the League is supporting this.
