A Sanzar spokeswoman said only the ruck incident was looked at and it was decided it didn't meet the "red card threshold".
To add insult to injury for Lam, Coles is free to play at Eden Park, while Braid will be kicking his heels.
"I'm really disappointed with the consistency of the citing commissioner," he said. "I mean, to have Dane Coles out there this week and openly admit to what he did, and we all saw it, and Luke's one when you have a look at it is pretty innocuous, so, pretty gutted about that.
"I think the citing commissioner has to look at himself. It's for everyone to see. Luke has to take responsibility for what he did but to look at what the other player did clearly and for him to admit that, I don't know what the citing commissioner was doing."
Lam also had a pop at a schedule, which gives his side a tight turnaround after arriving home from South Africa late on Sunday. Yesterday's training run was the first time the squad had assembled since. They will have time for only one more training session - a captain's run today.
"Every team which comes back from Africa gets a Saturday game [usually]," said Lam. "We've been given a Friday game which is tough, but we've just got to embrace that and get on and perform as a group."
Lam has named Piri Weepu at first-five against his former franchise, with Gareth Anscombe, who broke his nose in last weekend's defeat by the Stormers, on the reserves' bench.
Wings Rudi Wulf and David Raikuna return from injury, with Liaki Moli playing his first game for the Blues as Anthony Boric's replacement at lock.
Team doctor Stephen Kara said Boric could return in two weeks - the Blues have a bye next weekend - and Mealamu will miss only one week.
Wing George Moala has a shoulder injury but could get a run during the Blues' bye weekend, while Rene Ranger is serving the second game of a two-week ban.
