Nah. He's lucky there weren't charges filed, though Hayes would have never wanted that either. Hayes sucks, and it's a big fail by his editors too for publishing it in the first place, but you can't be a pro athlete physically engaging with a journalist, whether you are Brett Myers or Joel Embiid. And he (Hayes) had already apologized for the stuff about Arthur specifically online (along with deleting it) and was trying to do so there too. Embiid specifically called him out for not showing up at the Friday press conference (which was called at the last minute) and then he showed up. The Sixers brass (both Morey and Brand) knew Hayes was going to be there and the first thing they did after it happened was meet with Hayes to apologize for what Joel did. So I'd say between that and this whole mess about Joel's injury or non-injury we should be more worried about what's going on with this team, not the sportswriter. If Marcus Hayes can get in your head you're as flawed a player as Marcus Hayes thinks you are.
It would have been hilarious if he was suspended for games he wasn't going to play anyway, but somehow the NBA intends to make sure that it doesn't begin until he's ready and able to play. But, load management either way. Will cost him $1,000,000, maybe we can have a GoFundMe.
