I'm not fond of Paul George so much as well, even though he is a spectacular player, I don't find him a very much of a team player and he doesn't carry the team like a star that he is trying to be. But he is indeed the core of the team and very important for Clippers. His absence is very very important. According to ESPN, he has torn UCL, to be re-evaluated in 3-4 weeks. Which means surely Clippers are expected to have some hard time.
3-4 weeks is just for evaluation, another more weeks to treatment, and another more weeks for rehabilitation and recovery. Plus after he will be cleared to play, other weeks again for training. To sum it up, more likely at the end of the season.
Los Angeles Clippers fans should conclude already that Paul George might be out for the remainder of the season. He is one of the best players in the league that is injury-prone in the league.
Injury issues really sucks but can't be avoided.
