Marink Reedijk's first game as Hibernian manager ended in a Scottish Premiership defeat as his side went down to Dundee United at Tannadice.
Daniel Bennie's first-half strike proved decisive, with Hibs reduced to 10 men late on as substitute Jacob Devaney was shown a red card for denying Neil Farrugia a goalscoring opportunity.
United took the lead 35 minutes in when Lyall Cameron's dangerous ball was bundled over the line by Bennie.
Jesse Randall had earlier been denied twice when clean through on goal, with Hibs goalkeeper Raphael Sallinger standing tall on both occasions to deny him.
Reedijk looked to shake things up with a triple change early in the second half, introducing Rabbi Matondo for his Hibs debut.
The former Rangers winger almost made an immediate impact but was foiled by a tremendous last-ditch tackle by Michael Forbes.
Hibs continued to push for a leveller, but were vulnerable on the counter and Devaney was caught out when Farrugia raced in behind.
He nudged the United substitute in the back and while referee Don Robertson initially awarded a penalty and yellow card, he changed it to a free-kick on the edge of the box and upgraded Devaney's punishment to red after consulting the VAR monitor.
United passed up opportunities to kill off the game with a second goal and they were almost made to pay when Martin Boyle had a chance at the death, but Jack Walton saved well to ensure the home side claimed the three points.
