A Karlan Grant strike once again got the Baggies out of jail in the 69th minute, as the winger grabbed his seventh goal in eight league games.
Grant eventually broke the deadlock after Hull refused to budge for large parts of the game, Jake Livermore intercepted the ball high up the pitch for Callum Robinson to square it, allowing the former Huddersfield Town man to tap home.
Grant McCann's outfit came to frustrate the Baggies, however, their lack of creative threat meant the Tigers attacking candle was often blown out.
The 19-year-old came into the line-up and provided width down the right-hand side along with working hard to give a well-measured amount of tenacity.
Although, it's seen as unlikely that the youngster will keep his place in the starting eleven due to the form of Furlong so far during the campaign.
The Tigers find themselves in an unfavourable position in the EFL Championship so far this season, sitting in 23rd in the table.
Hull are also the lowest scorers in the division and it's clear to see why after an uninspiring attacking performance.
Scoring nine goals in 16 games means McCann's City team will struggle to propel themselves out of the relegation zone before the end of the season.
The Tigers have lost their last five second-tier games, heightening the pressure on McCann to turn things around.
The Tigers will face up against fellow strugglers Barnsley who sit a place above them in the table, an encounter that could make or break either one of their seasons.
The Tykes have recently sacked manager Marcus Schopp who departed the club following a shocking run of form.
