Hibs played out a 3-3 draw at the club's training ground in a behind closed doors friendly on a goal packed afternoon.
Gosling shone in the centre of midfield as he played for the first time since suffering cruciate knee ligament damage against Wolves last March.
Eyes were on the Devon-born player who put in good display and he managed to get through 70 minutes of action as manager Alan Pardew looked on.
Danny Guthrie who had a hand in all three United goals.
Newcastle opened the scoring when Phil Airey rose high to glance home Guthrie's swirling set-piece from the right wing mid-way through the first half.
Defender Jeff Henderson made it 2-0 at the start of the second when Guthrie curled in again, this time from the left, and Nile Ranger knocked it into the path of the Geordie Academy product to bundle home.
Daryl Duffy pulled one back in the second half but it was Dan Leadbitter levelled when he put one past his own keeper.
With 10 minutes to go, Guthrie bent in a free-kick to the far post from the left and Henderson got the final touch to make it 3-2.
However, a late twist resulted in Duffy salvaging a draw.
