Shearer accuses his team-mates of not trying
The Magpies had been lucky to recover from 2-0 down to 2-2 at half-time, but Wolves' determination and energy saw them claim the winning goal to see off the Premiership side.
Shearer said: "Not enough of us were putting the effort in today. I've lost count of how many times we have got ourselves back in the game this season and then committed suicide again. It is very disappointing but I have to say they deserved it. They played very well and we presented them with some great opportunities and they took them."
