4 running backs who have to step in immediately after Isiah Pacheco's injury

The Kansas City Chiefs have had some unfortunate visits from injury in recent weeks. After starting the season with the news that speedy, veteran wide receiver Marquise “Hollywood” Brown would miss the regular season due to his shoulder injury, running back Isiah Pacheco will also be out for quite some time.

Pacheco reportedly suffered a broken fibula in the Chiefs' narrow win over rival Cincinnati Bengals. While he will undergo further tests, the Chiefs appear to be prepared for the seventh-round gem to miss a number of games. He would miss at least four games if he is placed on the injured list.

The Chiefs' passing game hasn't been nearly as effective as many had hoped in recent weeks, which puts even more of a spotlight on Pacheco's responsibility. Will the Chiefs be able to adapt?

The Chiefs could look to the free agent market for a replacement, but Andy Reid has often had success finding replacements from within. Any of these four players could be used as backup to No. 10 until he is fully healthy as the schedule tightens.

While the Chiefs didn't really consider bringing McKinnon back despite his contribution to championship teams in the past, no free agent on the thin market has as much experience and exposure to Reid's offense. While he's an underdog, if the Chiefs hit the open market, he makes the most sense.

Perine could join his cousin Samaje in Kansas City's backfield. The former Jets draft pick hasn't been able to make an impact in the open field due to a lack of speed, but he could be a better option when it comes to gaining yards. Perine, who has been passed around the league a lot, has averaged 3.6 yards per carry in the pros.

If anyone ever needed a boost from the Patrick Mahomes aura, it's Ingram. After averaging just 2.2 yards per carry in his limited playing time with the Cardinals, Ingram will look to bring his proven running style to Kansas City. The Chiefs seem to have a penchant for getting the most out of sluggish, one-sided backs. He's also already on the practice squad.

Bailey, also on the Chiefs' practice squad, is a small running back at 5'7″, but his play at TCU was truly electric. Bailey ran for 1,209 yards and scored eight touchdowns in his final season with the Horned Frogs. While his 40-yard dash speed was average (4.58), he plays much faster. Of all the options, Bailey has the highest upside.
