Jaromir Jagr left Thursday's practice because of "soreness," according to a Devils spokesperson. He begun the session on a line with Travis Zajac and Patrik Elias, but headed off after only two line rushes and roughly 10 minutes of work. These type of injuries are fairly common at the start of training camps, but New Jersey would be wise to monitor the 41-year-old's playing time this year to avoid situations like this in the future.
