The Falcons elevated Muse from the practice squad to the active roster Saturday, Will McFadden of the team's official site reports.
Muse was likely elevated as an additional blocker for field-goal attempts and PATs. The entire Falcons tight end corps, consisting of Kyle Pitts, Charlie Woerner and Austin Hooper is fully healthy, meaning Muse will likely be useful only as a special teams addition during Sunday's contest with the Steelers.
