There is a goalkeeper pool in MLS this year, and Charlie Lyon is the only person in it:— Jonathan Tannenwald (@thegoalkeeper) May 3, 2019
Union sign Charlie Lyon as emergency goalkeeper with Andre Blake and Matt Freese injured https://t.co/uGpzalAOyu via @phillydotcom
Lyon, 27, played for LAFC last season and spent his first two seasons in MLS with the Seattle Sounders, though his 2019 contract option was declined and he most recently worked out with for Timbers 2, Portland's USL Championship side.
Philly have called on Lyon because of injuries to first-choice 'keeper Andre Blake and his understudy Matt Freese, the latter of whom had to exit Wednesday's 2-0 win over FC Cincinnati with an oblique problem.

Out 4-6 weeks.
Curtin hopes to have Blake by the Seattle home game.
Pool goalkeepers are available to MLS teams on an emergency basis when a team has fewer than two rostered 'keepers available for match action.
