Jagr left the ice on the first day of on-ice activity Thursday with soreness. At the time, coach Peter DeBoer didn't seem worried.
"I'm not overly concerned about it, but because time is definitely on our side we'll err on the side of caution," DeBoer said Thursday.
"I think there are different types of soreness; it's a different level when you step out onto the ice and it's not the first time I've dealt with guys who had aches and pains on the first day," DeBoer said. "It's a long summer and especially with the older guys. It sometimes takes a little longer for the body to get used to things that quickly."
