The team announced Friday it waived the former No. 2 overall pick with an injury designation. Robinson missed the past two games with an ankle injury.
Robinson continued his career-long struggles in Detroit before suffering the ankle injury. For reference, Pro Football Focus rated Robinson their 71st tackle this season out of 78 eligible players.
Waiving Robinson is a good indication the team will get Decker back from the physically unable to perform (PUP) list soon, possibly before Sunday's game versus the Cleveland Browns. Decker's return will be a huge boon for Matthew Stafford's blind side.
