A late equaliser denied South Shields a superb Buildbase FA Trophy first round win over National League North side Southport at Mariners Park.
After going in at half-time a goal behind, a pulsating second half performance from the Mariners put them 2-1 ahead.
Gary Brown equalised before Jason Gilchrist netted what looked like it might be the winner against his former club.
Southport hit back with an equaliser from substitute Raul Correia, though, meaning the teams will have to do it all again in a replay at Haig Avenue on Tuesday.
The suspended Nathan Lowe was replaced in the Shields line-up by teenager Arron Thompson in the only change made by Lee Picton and Graham Fenton to the team which drew 1-1 with Warrington Town in the league a week earlier.
They started on the front foot against a Southport side which sits fourth in the National League North.
Gilchrist fired a dangerous low ball across the area from the left which narrowly evaded a touch and a lob from Robert Briggs just failed to clear visiting goalkeeper Charlie Albinson.
The Sandgrounders did not threaten the Shields goal before taking the lead against the run of play on 14 minutes.
It was a clinical moment from the away side as Bradley Bauress peeled off into some space on the left and delivered a terrific cross which Jack Sampson powerfully headed past Myles Boney.
Shields regrouped and had an opportunity to equalise 10 minutes later when Briggs found Gilchrist on the right of the area and he drilled an effort wide.
At the other end, Boney made a smart stop from Sampson, who also had a shot deflected wide as Southport looked to double their advantage.
The score remained unchanged heading into half-time, after which the Mariners cranked up their performance and applied consistent pressure on their opponents.
Gilchrist had a header saved after a good link-up with Jon Shaw and Brown had an effort kept out by Albinson after he got on the end of a Briggs free-kick.
Thompson struck over from distance as Shields continued to press, and they got their reward in the 66th minute when a deft cross from Phil Turnbull was met by Craig Baxter and saved by Albinson before Brown rammed home the rebound after responding quickly.
The Mariners sensed blood and just seven minutes later found themselves in front when Turnbull fed a superb ball through to Gilchrist on the right of the box and he finished coolly with a dink as he netted the goal he had been threatening.
At that stage there appeared only one winner but the withdrawal of Brown with a dead leg unsettled Shields somewhat, despite his replacement Will Jenkins making an impressive contribution.
Captain David Morgan could have equalised with 10 minutes left for Southport but fired wide from 12 yards.
The visitors did draw level soon after, though, when Shields failed to clear a corner and after a short scramble substitute Raul Correia slammed the ball home.
There were chances at both ends for a winner, with superb blocks denying Gilchrist and Millenic Alli for the Mariners, and Boney producing an excellent save as he pushed a header onto the bar.
The final whistle signalled the end of a thrilling cup tie and the teams will now have to do it all again on Tuesday, with Southport this time enjoying home advantage.

Striker Jason Gilchrist has become South Shields’ latest summer signing after joining on a permanent deal from National League North side Southport.
The 24-year-old has been a prolific goalscorer throughout his young career to date, and was the National League North’s top scorer in the 2017-18 season, when he netted 26 times.
South Shields joint manager Lee Picton said: “We are delighted to bring Jason to the club.
“He is someone we have tracked for a while and he has a proven goalscoring record at this level and higher.
“We feel he is a great fit for what we are looking for moving forwards at the club.
“We’re really confident he will suit our style of play, and have been very impressed with him as a person during the conversations we have had with him.”
Gilchrist came through the Manchester City youth system and played for the club for 10 years after joining at the age of six.
He then moved on to Burnley, scoring over 50 goals in three seasons for the Clarets’ development teams.
Senior football followed for the striker at Droylsden, Accrington Stanley and Chester before FC United of Manchester swooped to sign him in the summer of 2016.
He scored 29 goals in 15 months before moving onto Southport in November 2017, a season which he would end as the league’s top goalscorer.
Gilchrist spent the tail end of last season with Stockport County, who won the National League North title during his time at the club.
Welcome to South Shields, Jason!
