The Heat first embarked on their winning run back in early February after a loss to the Indiana Pacers and were only six games away from equalling the Los Angeles Lakers' record of 33 wins in a row back in 1971-1972 with a series of sensational performances which saw them come from behind to overturn fourth-quarter deficits 11 times in the streak.
However, even LeBron James' 32-point contribution came to naught against an organised Bulls side who were missing 2011 NBA MVP Derrick Rose and All-Star center Joakim Noah. Luol Deng fired in 28 points and Carlos Boozer, who added 21 points and 17 rebounds, were the key men for the Bulls as theycapped off an impressive defensive performance at the United Center.
The Bulls took an early double-digit lead but it was whittled down to a single point in the third quarter to set up a nervy final period.
It was then that Tom Thibodeau's men put up a gritty defensive performance to see out the game in a physical final few minutes that saw a frustrated James collect a flagrant foul.
Despite the loss, the Miami Heat are still leading the Eastern Conference standings with a 0.789 win percentage and are likely to secure first seed for the playoffs and James was less concerned about the streak than about the team's prospects on winning the NBA title.
The 2012 NBA MVP was quoted as saying after the game: "We weren't pressing every game to get that streak. We were just playing each and every game to win, and we happened to win 27 games in a row - we didn't really think about it [the streak]."
"We haven't had a chance to reflect on what we just did. We're fortunate, and humble to be part of a streak like that. It's one of the best in the league and we recognise it so.
"We want to win the NBA. Along the season, this is just one of the things we will look back at and remember on."
