Pompey suffered their first league defeat of the season after going down 4-2 at Carlisle today.
Michael Appleton’s men were left to rue poor marking as the hosts went two goals ahead through Jake Jervis (13) and Danny Livesey (47) headers.
The match looked all over when Kevin Long was sent off for two yellow cards late on.
But in a frantic finish, the Blues reduced the deficit when substitute Ashley Harris nodded home from Liam Walker’s corner on 88 minutes.
Carlisle looked to have it wrapped up as James Berrett made it 3-1, only for Conor Clifford to give Pompey a lifeline in injury-time.
But as the visitors piled men forward, the Cumbrians sealed all three points with seconds left when Paddy Madden picked up a rebound to slot home.
It leaves Pompey on two points from their opening three matches, with the 10-point deduction expected to come once they are out of administration.
