NEIL Harris explained why he brought off Steve Morison and Lee Gregory with 15 minutes left against Brentford on Saturday – and then joked he would have a "chat" with Tim Cahill after another yellow card for the Lions legend.
Cahill, 38, picked up a booking moments after coming on in the 1-0 win, after earning a yellow card seconds after his introduction against Hull last Tuesday.
Saturday's caution was his third in his last four games, indicating Cahill's keenness to make an impact with Millwall defending leads late on.
Cahill had come on for Ben Marshall, after Fred Onyedinma and Tom Elliott were sent on to give Millwall extra attacking energy.
"Lee and Steve are great at defending from the front, they have been for the last three years," Harris said. "I just thought they looked a little bit leggy, we didn't really have an out ball.
"It was a bit of a risk to take both experienced strikers off and bring a young partnership on. I thought it gave us more of a foothold for five or six minutes. But then you've got players tiring in other positions, Marshy and Jed looking leggy in wide areas.
"You turn to your bench and you've got a 38-year-old Millwall legend who's got more than 100 caps. He's the perfect person to bring on. We'll have a chat with him about another yellow card again!
"It's great to be able to bring him on when we're in that position. He knows what it takes. He came on and lifted the crowd. He put himself about and chased lost causes. I thought him, Tom and Fred were outstanding when they came on the pitch."
The Lions moved above Brentford with the win, in an electric atmosphere at The Den.
Harris said: "Both sets of fans were outstanding, and rightly so because both teams have done well this year. Our fans are on cloud nine at the moment because of how their players are playing.
"We've massively overachieved so far and will try to continue to do that. Brentford have been on a great run of form. They played very, very well and have some brilliant young players.
"It's two clubs in a great position."
