According to Field Yates of ESPN, the Redskins worked out free agent RBs Ronnie Hillman and Daryl Richardson on Monday.
This comes after Rob Kelley suffered a high-ankle sprain and an MCL sprain Week 10 against the Vikings.
Hillman, 26, is a former third-round pick of the Broncos back in 2012. He played out his rookie contract before re-signing with Denver on a one-year, $2 million contract this past April. However, the Broncos cut him loose at the start of last season.
The Vikings later signed him to a contract after sustaining some injuries at running back.
