Allan Moore's men travelled through to Tranent to meet the Easter Road side for a midday kick-off in the first of two bounce matches.
Afterwards, the Ton boss, inset, admitted he was pleased with how his side had performed, declaring the match a worthwhile exercise.
He said: "We lost 5-2 to a Hibs team including all their first team players. Garry O'Connor, Ivan Sproule - you name them, they were playing.
"We were 2-0 down after five minutes and I was thinking, 'here we go, we're going to get hammered', but the boys fought back well and got a couple of goals.
"Peter MacDonald scored two good goals. One was a nice lob and the other came direct from a free-kick.
"We had Andy Graham and Ross Forsyth playing at full-back, and they were a wee bit too adventurous at times against a side like Hibs, leaving us exposed.
"But these games are for putting things like that right, so we pointed that out to them and they'll have learned a lesson.
"Michael Tidser had a decent game in the middle, as did the big boy Josh Knight we have up on trial from West Brom.
"Hibs changed their whole team at half-time and knocked the ball about well, so it really was a worthwhile exercise."
In the second of the day's fixtures, an entirely different Morton line-up met Airdrie United in another closed-doors game.
And while the Cappielow men were beaten 4-1 by the Diamonds, Morton number two Mark McNally insisted he was pleased with the workout.
He said: "We were drawing
1-1 against Airdrie with around 10 minutes to go, but conceded a penalty and a few late goals and eventually lost 4-1.
"By the end, we had made some changes and had several trialists, under-17s and under-19s on the park, but just two signed players.
"We won't really be reading anything into the scoreline as these matches are fitness exercises -they're not about results.
"Stuart McCaffrey and Peter Weatherson got 90 minutes under their belts, while Paul Di Giacomo, David O'Brien and Andy Jackson all played around 50 to 60 minutes.
"Darren McGeouch played well for the 60 minutes he was on, scoring our goal, and Gavin Skelton got the full match and was also impressive.
"Tonight was pleasing from that perspective and should prove to be an important workout that will stand us in good stead for the season ahead."
