Watch: Thompson lashes out at LeBron in 2nd OT

It's clear the Cleveland Cavaliers are ironing out issues with their defense after allowing 130 points Sunday to the Indiana Pacers, who sit in ninth in the East and entered play on a three-game losing streak.

Though the Cavs won in double overtime, the tension between two Cleveland players was very public.

Tristan Thompson and LeBron James got into a heated exchange of words with less than 30 seconds to go as they headed into a timeout.

James apparently wasn't happy with Thompson's defense, and the situation escalated on the sideline.

Despite the incident, Cleveland held on for a 135-130 victory.
