PHOTO: Penguins' Crosby ready to play despite apparent illness

The term sick day doesn't apply to Sidney Crosby. 

Or perhaps he's just stocking up for another long, cold winter.

The Pittsburgh Penguins superstar returned to practice in advance of Friday's game against the Calgary Flames, after sitting out the previous day due to an apparent illness.

And when we say apparent, we mean very apparent.

Nevertheless, Crosby confirmed that he'll be in the lineup for Friday's tilt with the Flames, and dispelled any notion that he's contracted a case of the mumps.

We'll take your word for it, Sid.
