Gallman, 26, took on a bigger workload last season after Saquon Barkley suffered an ACL injury during Week 2. Gallman finished the season with 147 carries for a career-high 682 rushing yards with six rushing touchdowns through 15 games with New York in 2020. He added 21 receptions for 114 yards.
The Giants made Gallman a fourth-round selection out of Clemson in 2017. He has 1,444 rushing yards on 338 attempts with nine rushing touchdowns through his four NFL seasons.
