Wallace previously worked out for the Seahawks back in July.
Wallace, 23, wound up going undrafted out of Arkansas back in May. He later agreed to a three-year, $1.755 million contract with the Broncos.
However, Denver elected to cut Wallace loose a month later and he later caught on with the Redskins. Washington waived him in July.
