United were beaten 2-1 by Bundesliga side FC Energie Cottbus, with Tresor Kandol getting a goal back just after half-time.
However, the main talking points of the game came with around 20 minutes remaining, when former Blackburn midfielder Douglas was shown a straight red card for dissent, then two minutes later Beckford was shown a second yellow card, once again for dissent.
This prompted Wise to beckon his players to the touchline, and after a short discussion between players and management, the game continued.
However, shortly afterwards Poyet's protestations led to him being sent to the stands.
