Bostic (pectoral) was placed on injured reserve Friday.
Bostic is officially done for the regular season after being transitioned to IR on Friday following the pectoral injury he suffered in Week 16 against the 49ers. The linebacker will finish the regular-season campaign with 25 tackles while appearing in 15 games with the Commanders. De'Jon Harris was signed to Washington's active roster from the practice squad Friday and will provide the team with an additional depth option at linebacker in Bostic's absence.
