Millwall boss Neil Harris stated that Tuesday night's 2-2 Sky Bet Championship draw with Queens Park Rangers at Loftus Road was "a good point," but he was disappointed for his players that they couldn't see the game out.
On a controversial night in west London, Conor McLaughlin gave The Lions an early lead before Lee Gregory was shown a straight red card shortly before the half-time break.
Jed Wallace nudged Millwall into a 2-0 lead on 50 minutes, but late goals from Massimo Luongo and Matt Smith secured a point for The R's.
"It's a good point," said Harris. "I'm really proud of the character and the performance. For 40 minutes, at 11 v 11 - what a great away performance.
"It's a good point, but I'm disappointed for my players that we couldn't see the game out."
The manager questioned Roger East's decision to send Gregory off, stating the challenge was "a yellow card at the very most."
"We got our noses in front and could have had three of four more. I was disappointed not to be out of sight, to be honest, but then the red card comes. At the time and having seen it back, plus talking to my players on the pitch - no one can believe it's a sending off.
"To get to 2-0 in front was a real bonus and it gave us a real opportunity to hang on, as QPR put us under a lot of pressure. They played some lovely football and they hit the big man well. Unfortunately, it wasn't to be and we've had to settle for a point.
"Lee is feeling really aggreived. He's not that sort of player to even make tackles, let alone malicious ones. His reaction, plus Steve Morison and Shane Ferguson's - two of the most honest players we have - plus some of their players couldn't believe it. It's a yellow card at the very most. If anything, it's a 50/50 ball.
"To be a red card in the modern game, it's got to be dangerous and malicious - it wasn't."
