British and Irish Lions stand-in captain Rory Best conceded that his side were well beaten up front in their loss to the Brumbies.
Issues for the Lions at the set-piece compounded their efforts in a disappointing first-half performance, the tourists only posing a true threat after the introduction of several replacements.
The Brumbies' hard work at the breakdown and greater physicality ultimately sent the Lions packing, with Best stating that his side "just didn't turn up."
Few of the side fielded against the Brumbies can now expect to play a role against Australia in the 1st Test on Saturday.
"We got physically beaten up up front, they put a lot of pressure on the set-piece and we got a bit nervy, and all credit to the Brumbies they were hungrier than us right across the board," said Best.
"We were feeling very confident, we knew it was going to be a tough task but we just didn't turn up tonight. Right from the very off they just wanted it more, they took their chances and you have to give them massive credit.
"I don't think we're looking for excuses, we brought in quality players. When you looked across the team we had a quality team, we just got beaten up at the breakdown tonight.
"We definitely got nervy. At this level if you can't secure that ball you're always going to be under pressure.
"The forwards will stand up and take a lot of the heat, and deservedly so. We let our standards drop tonight and it'll be up to the 15 and 23 guys picked this weekend to raise those again.
"We didn't want to lose the momentum that we've gained on the tour, but we've done that and now we have to dust ourselves down and see where we go from here."
