Neil Harris has bemoaned referee Lee Probert’s decision to give Millwall a penalty - just seconds before Lee Gregory scored.

Jed Wallace was fouled in the box eight minutes from time, but Probert did not play the advantage, which meant Gregory’s fine finish counted for nothing. Gregory then missed the resulting spot-kick, much to the frustration of the Lions boss.

The striker, who netted a penalty against Barnsley last weekend, wasted the opportunity to draw Millwall level after Brentford had taken the lead through Romaine Sawyers.

As a result, Millwall succumbed to a second successive defeat.

Harris said: “The second one is the Shaun Hutchinson decision. He toes the ball past the lad and he steps on his foot. Unfortunate incident, but it is a penalty.

“Unfortunately for us, that moment probably kills the next one because the referee knows he has got it wrong and so quickly gives the next incident before it breaks to Lee Gregory.

“Lee [Probert] has been good enough to see me. He is a smashing fella and I think a top referee as well and has just said to me if it is a penalty he must give it really.

“I disagree, I think he can buy himself a split second to see where the ball falls. He didn’t. He probably gives it because he did not give the one before. I said to him, it is what it is.”

Harris continued: “If it is a rule that you must give a penalty quickly and can’t play advantage in the penalty area, it is a rule that I am not aware of and I have played the game for 40-years now.

“I will have to check my rule book for that. But, if Gregory scores the penalty then we are not having this conversation.”
