Mike Klis confirms the news and adds that the Broncos are also promoting OL Austin Schlottmann.
This comes a day after Broncos ILB Baron Browning was added to the injury report.
Robinson, 23, wound up going undrafted of Stanford back in April. He later signed a three-year, $2.4 million contract with the Broncos.
Denver waived Robinson coming out of the preseason before re-signing him to their practice squad.
During his college career at Stanford, Robinson recorded 143 tackles, four sacks, an interception, three forced fumbles, a recovery and five pass deflections over the course of four seasons and 31 games.
