The Miami Heat go on the road to San Antonio on Sunday fighting for survival in the NBA Finals 2014 series. Game 5 is a must win game for the Heat after they were blown away by the San Antonio Spurs in Miami, and they no longer have any room for any more mistakes.

Game 5 takes place from the AT&T Center in San Antonio, Texas with a scheduled start time of 8 p.m. EST. The game will be broadcast on the ABC network, and will also be available to watch online through live stream via the link provided below.

The Heat have a mountain to climb after losing Game 4, and now must make history by performing the greatest comeback in NBA Finals history since 1950. No NBA Finals team has come back from a 3-1 deficit since the championship series began 64 years ago, so the Heat have put themselves in a position where they must break records to retain their title for a third straight season.

Coming into this game at 1-3, LeBron James and co. know they need to win three straight games if they are to snatch the title back from the Spurs' grasp.

"We put ourselves in position where it is about making history," James said after the Heat's Game 4 defeat.

Making it even more difficult, two of the three remaining games will take place in Texas, so the Heat will have to do a majority of their work on the road. The massive task can see clearly seen when considering the Spurs' record at the AT&T Center this year; they are 10-2 in San Antonio this postseason, although one of those losses did come in this NBA Finals series.

The Miami Heat against the San Antonio Spurs will be shown on the ABC network with a tip-off time of 8 p.m. ET. The game can be watched online by clicking here.
