Michael Phelps helped earn America the gold on Sunday, and now it's time to see if the 23-time medalist is inline to repeat the feat. Eight members of Team USA will look to become the best in the world on Monday night, but all eyes will be turned to Phelps' qualifier.

America's most decorated Olympian retired following his record-breaking streak in London, but it wasn't long before Phelps was back in the water. Sunday saw the swimmer lead Nathan Adrien, Caeleb Dressel, and Ryan Held to victory in the men's 4x100m freestyle relay, and tonight the 31-year old will start his road to a potential 20th gold in the heats for the men's 200m butterfly at 10:19 p.m. ET.

Meanwhile, Conor Dwyer, Townley Haas, Lathleen Baker, Olivia Smoliga, Ryan Murphy, David Plummer, Lilly King, and Katie Meili will each attempt to secure a place on the podium. 

Starting at 9:21 p.m. ET, Dwyer and Haas will race in the men's 200m freestyle final before Baker and Smoliga take on the women's 100m backstroke at 6:30 p.m. ET. Swimming fans shouldn't change the channel once the women's times are in - Murphy and Plummer will compete in the men's 100m backstroke at 6:38 p.m. ET while King and Meili will hit the water at 6:54 for the women's 100m breaststroke finals.

Be sure to catch all the action with NBC's swimming live stream, which will start at 9 p.m. ET right here.
