Eagles' Johnson selling underdog shirts for charity

Philadelphia Eagles right tackle Lane Johnson is using the team's underdog status to support a good cause.

On Monday, Johnson unveiled a limited-edition T-shirt featuring him and Chris Long in dog masks with the phrase "Home Dogs Gonna Eat." The shirts are being sold through Johnson's website for $18, with all proceeds donated to the Fund for the School District of Philadelphia.

The Eagles are allowing dog masks to be worn inside Lincoln Financial Field for Sunday's NFC Championship Game against the Minnesota Vikings, though fans may have a hard time finding them online.

Amazon quickly sold out of the German Shepherd masks Johnson and Long wore following the Eagles' divisional round win over the Atlanta Falcons, and CreepyParty, the company that makes the masks, told ESPN's Tim McManus they're struggling to keep up with the demand.
