Both players were considered high-risk contacts to K Graham Gano, who tested positive last week.
Dixon, 27, is a former seventh-round pick of the Broncos back in 2016. The Broncos traded him to the Giants during the 2018 offseason for a conditional seventh-round pick.
Dixon was in the final year of his four-year, $2.42 million contract when he agreed to a three-year extension with the Giants last year.
In 2020, Dixon has appeared in 10 games for the Giants and totaled 1,591 yards on 36 attempts (44.2 YPA), which includes 21 downed inside the 20-yard-line.
