Steelers sign K Josh Lambo to practice squad

The Pittsburgh Steelers signed kicker Josh Lambo to their practice squad Tuesday with Chris Boswell in the concussion protocol.

The team also added defensive end Taco Charlton to the 53-man roster to fill the spot of Melvin Ingram III, traded earlier in the day to Kansas City.

Lambo is insurance in the event Boswell doesn't clear the concussion protocol in time for the Week 9 game against the Chicago Bears on Monday nig
