The Philadelphia Flyers got their first real road block of training camp so far. 

Starting goalie Carter Hart was forced to leave practice earlier this week and wasn't able to return. 

Hart hasn't participated in scrimmages since then but did take some shots from teammates on Thursday. 

The Inquirer's Sam Carchidi reveals that Hart has been dealing with back spasms. 

While he's sidelined at the moment, it's believed that Hart should be ready for the opener on August 2.
