Technical Stoppage
Any player who recognises a condition that endangers players may call "technical" to stop play. Play must stop immediately.
The thrower may call a technical stoppage during play to replace a severely damaged disc.
A severely damaged disc is one that is cracked, torn, deeply gouged, creased, punctured or badly warped ("tacoed"); a slightly warped wet or dirty disc does not qualify. However an existing stoppage may be extended to correct a warped disc (rule 10.3).
