As we move into Week 4 of the NFL season, it's more important than ever to be tinkering with your fantasy roster. Not only are we starting bye weeks—the New York Jets and San Francisco 49ers are both off this week—but there has been a plethora of injuries around the league.

Depending on how heavily your roster has been hit, you may have to go deep into the waiver wire in Week 4. Here, we'll examine some deeper targets—owned in 35 percent of Yahoo leagues, according to FantasyPros—that you may even be able to snag with a second waiver-wire claim.

Deep Sleepers

Darrel Williams, RB, Kansas City Chiefs, 7 percent

T.J. Yeldon, RB, Buffalo Bills, 3 percent

Diontae Johnson, WR, Pittsburgh Steelers, 4 percent

Kyle Allen, QB, Carolina Panthers, 3 percent

Jacoby Brissett, QB, Indianapolis Colts, 21 percent

Daniel Jones, QB, New York Giants, 18 percent

Wayne Gallman, RB, New York Giants, 7 percent

Preston Williams, WR, Miami Dolphins, 7 percent

Rex Burkhead, RB, New England Patriots, 25 percent

Phillip Dorsett, WR, New England Patriots, 33 percent

Darrel Williams, RB, Kansas City Chiefs

Last week, the Kansas City Chiefs were without running back Damien Williams. They were also without LeSean McCoy, who aggravated an ankle injury. Darrel Williams stepped in and produced 109 total yards with five receptions.

McCoy's injury isn't believed to be serious, as Chiefs coach Andy Reid noted.

"LeSean McCoy retweaked his ankle a little bit, but I think he will be back and fine as we go here," he said, per Charles Goldman of Chiefs Wire.

However, we're likely to see another split between McCoy and Darrel Williams against the Detroit Lions this week. That's good news for McCoy and Darrel Williams owners, as the Lions rank just 22nd against the run (125.3 yards per game allowed).

Phillip Dorsett, WR, New England Patriots

New England Patriots wideout Phillip Dorsett is worth a top waiver claim, and he's going to be a popular target coming off a six-catch, 53-yard, one-touchdown performance.

His value goes beyond what he produced in Week 3, though. It's clear the Patriots plan to make him a focal point of their passing attack moving forward. In the two games in which New England didn't have Antonio Brown, he racked up 10 receptions, 148 yards and three touchdowns.

Fellow wideout Julian Edelman is day-to-day with a rib injury, so Dorsett could have an even bigger role in the immediate future.

Now, Week 4 doesn't present the best matchup for the 26-year-old. The Patriots are playing AFC rival Buffalo on the road. The Bills have been solid against the pass, allowing just 211.7 yards per game and 5.5 yards per pass attempt.

Tom Brady is likely to nickel-and-dime his way down the field, which is better for James White and Rex Burkhead than it is for Dorsett. However, the Miami product is worth a flex start in deeper leagues and is definitely worth picking up for future use.

Diontae Johnson, WR, Pittsburgh Steelers

If you're looking for a player to start specifically in Week 4, Pittsburgh Steelers rookie wideout Diontae Johnson is a solid target. The Steelers were fed up with Donte Moncrief's drop issues and made him a healthy scratch in Week 3. 

This gave the Toledo product an opportunity, and he responded with three receptions, 52 yards and a touchdown.

This week, Johnson and the Steelers will host the Cincinnati Bengals, who have been atrocious on defense. They have allowed just 237.7 passing yards per game (12th in the NFL), but that number is misleading and a product of their 31st-ranked run defense (168.7 yards per game allowed).

The Bengals have allowed an average of 9.1 yards per pass attempt, which is the fourth-worst mark in the NFL. This means the 23-year-old will have big-play opportunities, even if the Steelers employ a run-heavy approach.
