Reggie Bush's injury could force fantasy football owners to look at their league's waiver wire to find a replacement for the Miami Dolphins running back.
According to ESPN's Adam Schefter, we will know more about the extent of Bush's injury on Monday:

Let's look at three running backs on the waiver wire that you should add to your fantasy team while Bush deals with his injury.
Daryl Richardson, St. Louis Rams
St. Louis Rams running back Steven Jackson was questionable going into Week 3 against the Chicago Bears because of a groin injury, but he ultimately ended up playing.
His backup is Daryl Richardson, who could see his number of carries per game increase if Jackson continues to struggle with injuries.
Richardson had four carries for 16 yards on Sunday, but in Week 2, he carried the ball 15 times for 83 yards and caught two passes for 19 yards.
Depending on his matchup, Richardson could be a good bye-week replacement as the season continues.
Tashard Choice, Buffalo Bills
The Buffalo Bills' injury troubles at running back could give Tashard Choice a chance to start in Week 4 against the New England Patriots.

However, be sure to monitor Jackson's progress throughout the week before picking up Choice for your team. Your decision to add Choice or not should be based on Jackson's status for Sunday's game.
“Fred will practice this week,” said [head coach Chan] Gailey. “I don’t know if it’ll be Wednesday or Thursday, but he should practice some time this week. His recovery has been amazing.”
The Patriots have allowed 226 yards rushing over the last two weeks, including a 101-yard performance by Baltimore Ravens running back Ray Rice on Sunday night.
With a 4.1-yards-per-carry average and several years of NFL experience, Choice is a very good waiver-wire pickup for Week 4.
Ryan Williams, Arizona Cardinals
To Ryan Williams' credit, he took advantage of his opportunity to shine when Beanie Wells was injured on Sunday.
Williams rushed for 83 yards on 13 carries against a good Philadelphia Eagles defense in Week 3, and if Wells continues to deal with a toe injury (via Darren Urban of Cards Chatter), then Williams might be a good fantasy option off the waiver wire.

Three of the next four games for the Cardinals are against run defenses ranked outside of the top 10.
