NEIL Harris felt Millwall were denied a "stonewall" penalty during their 2-0 loss to Watford – but admitted the decision might not have affected the result.
Ed Upson was bundled over in the area with the score at 0-0 but referee Simon Hooper ruled that the midfielder has gone to ground too easily.
The Hornets took the lead at the other end shortly afterwards when Matej Vydra drilled in a superb first-time volley from Ikechi Anya's floated cross.
"I think it's about as clear-cut a penalty as you're ever going to see," Harris said.
"I thought it was a stonewall penalty at the time and I've seen it back a few times as well.
"Ed gets between the ball and the player. The player makes an honest challenge for the ball but clatters Ed first without getting near it.
"It's a penalty and probably changes the swing of the game.
"Referees have difficult jobs and have to make decisions straight away. We got on with it and that's not what cost us the game.
"It might have helped us but it doesn't necessarily mean the result would've been any different.
"I asked Keith Hill, the fourth official, to ask the referee why [he hadn't given the decision], and he thought Ed went down slightly too easily.
"Watching it back, it's clear to see that he didn't. But he didn't give it and we can't change that."

The Lions were competing well with the third-placed visitors until Vydra's opener.
Adlene Guedioura then finished off a passing move to make it 2-0 in the second half.
"Vyrda's was an outstanding goal," Harris added. "As an ex-striker, I thought it was a great finish and a great volley.
"We can say that with both goals we could've defended slightly better but I think you have to give credit when credit is due."
Millwall battled hard to find a way back into the game, with Aiden O'Brien firing their best chance at Heurelho Gomes from a narrow angle.
"I'm pleased in a lot of senses," Harris added. "Between both penalty areas we were outstanding and I was really pleased about that.
"Everything that we're asking for from the players, they gave us again. The difference was the quality in the final third and that was clear to see.
"That's why a lot of the Watford players will be gracing the Premier League next season, with or without Watford."
The Lions, who remain seven points adrift of fourth-bottom Rotherham, face Wigan in a must-win six-pointer on Tuesday.
"We're at the stage when we need to win games and quickly," Harris said.
"We're giving everything we've got and we're constantly improving but it gets to the stage when you have to start winning games, and that starts on Tuesday.
"Wigan is a huge game for our club. It'll be a challenging evening but it's one we're looking forward to after a decent performance, albeit without an end product."
