Mason will be out of the lineup for Thursday's preseason matchup with the Rangers for the birth of his child, Sam Carchidi of The Philadelphia Inquirer reports.

EDGE Analysis

With Mason away from the team, the Flyers called up Anthony Stolarz from AHL Lehigh Valley who will likely man the clipboard behind Michal Neuvirth against the Rangers. Fantasy owners may want to be cautious picking up Mason as coach Dave Hakstol frequently flip-flopped between who his starter was going to be last year, especially down the stretch.
