Klis mentions that Bellamy is insurance at running back with Phillip Lindsay out this week.
Bellamy, 23, wound up going undrafted out of Western Michigan back in April. He later signed a three-year, $2.28 million contract with the Broncos, but was waived coming out of training camp.
The Broncos later added Bellamy to their practice squad and activated him last week.
In 2020, Bellamy has appeared in one game for the Broncos but did not register a stat.
