Sunday night featured a heroic Boston Celtics team on the ropes and on the road against the Cleveland Cavaliers. Down 0-2 and without Isaiah Thomas on the court for them, the Celtics looked pretty much dead in the water. However, the "Luck of the Irish" and the surging scoring power of Marcus Smart was on their side Sunday night. The Boston Celtics captured a huge 111-108 victory on the road to stay alive in the postseason and make it an extremely interesting series.

How the Celtics won

In a shocking turn of events, the 10-0 Cavaliers looked to continue their dominant postseason, as they'd return home to face a Celtics team down their top star.

However, Marcus Smart stepped in admirably for the No. 1 seed "underdogs."

Smart led all Boston Celtics' players with his 27 points on 8-for-14 shooting. Seven of those shots he hit were three-pointers and he also tallied seven assists, along with five boards and two steals. Teammate Avery Bradley scored 20 points, while Jae Crowder finished with a double-double of 14 points and 11 rebounds. The Celtics shot 46.2 percent from the floor and 45 percent from downtown.

The Cleveland Cavaliers looked like they were going to put their opponents away early as they led 35-24 after one quarter and 66-50 at the half. However, Boston battled back, outscoring them 61-42 in the second half to get the comeback win.

LeBron James was held to just 11 points on the night on 4-for-13 shooting. Kyrie Irving had 29 points on 10-for-15 shooting to go with seven assists, while Kevin Love and Tristan Thompson each recorded double-doubles. Love had 28 points and 10 rebounds, while Thompson had 18 points to go with 13 boards. The Cleveland Cavaliers shot 45.7 percent overall and 41 percent from three-point range.

When do they play again?

Can the Boston Celtics Shock The World a second time? They'll get a chance to win another big road game without Isaiah Thomas in a few days. Thomas is ruled out for the rest of the postseason, but it's clear that the Celtics are playing for pride's sake as the No. 1 seed.

Game 4 of this Eastern Conference Finals series will also be held at Cleveland's Quicken Loans Arena.

That game is scheduled for Tuesday, May 23rd at 8:30 p.m. Eastern Time, with TNT providing live televised coverage.

There will also be a Game 5, which is good news for faithful Celtics fans. That game will take place at the TD Garden in Boston on Thursday, May 25th, also at 8:30 p.m. Eastern Time, and also on TNT.
