Ageless New Jersey Devils forward Jaromir Jagr missed his club's practice with a serious illness on Monday.

The 42-year-old, who has managed nine goals and 25 points in 43 games for the Devils so far, is questionable to join the team for the start of its California road trip this week:

Lamoriello said at this point he does not know if Jagr and Ruutu will be able to accompany team to LA tomorrow. Both are pretty sick. — Tom Gulitti (@TGfireandice) January 12, 2015

An infamous rink rat, Jagr is loath to miss games. Despite his advancing age he's appeared in all but one of his club's contests since joining the Devils in the summer of 2013.
