Indianapolis Colts middle linebacker Shaquille Leonard is active Sunday and will make his season debut against the visiting Tennessee Titans.

The Colts also activated defensive tackle DeForest Buckner, who had been listed as questionable with an elbow injury.

The inactive players for Indianapolis are safety Julian Blackmon, quarterback Sam Ehlinger, cornerback Dallas Flowers, center Wesley French, wide receiver Dezmon Patmon, offensive tackle Luke Tenuta and defensive tackle Chris Williams.

For the Titans, the inactive players Sunday are defensive backs Ugo Amadi, Amani Hooker and Theo Jackson; linebackers Wyatt Ray, Ola Adeniyi and Zach Cunningham; and offensive lineman Le’Raven Clark.
