The 2022 NFL season is entering its fourth week and with Fantasy football injuries starting to pile up, owners are starting to turn to the Fantasy football waiver wire to bolster their Fantasy football rosters. The running back position took considerable damage last week with Dalvin Cook (shoulder), D'Andre Swift (shoulder, ankle) and David Montgomery (knee) all being forced to leave the game last week. All three were locks but now may need to be replaced in your Week 4 Fantasy football lineups.

So who is in line to benefit on those respective teams in the wake of the latest NFL injury news and what other options are available on the Week 4 Fantasy football waiver wire? Even if you aren't in dire need of a starter, it's imperative to optimize your bench on a weekly basis to improve your depth and undercut your ailing opponents. Before determining who to target on the Week 4 Fantasy football waiver wire, be sure to see what SportsLine Fantasy football analyst Jacob Gibbs has to say.

Gibbs uses a data-driven approach that has helped him consistently provide accurate rankings at every position. He has proven to be one of the nation's most accurate Fantasy rankers in recent years -- posting the eighth-most accurate results over the past three seasons, according to Fantasy Pros.

Now, he's revealed his top waiver wire pick from among the widely available Fantasy football free agents entering Week 4. You can see his top Fantasy NFL waiver wire picks and full analysis over at SportsLine

Top Fantasy football waiver wire picks for Week 4

One player Gibbs is advising Fantasy players to target on the Week 4 waiver wire: Bears running back Khalil Herbert, who is being rostered in just under 60% of CBS Sports Fantasy football leagues. Even before Montgomery were forced to leave last week's matchup with the Texans, Herbert had impressed the new coaching staff in Chicago during the preseason and was even the preferred option for the Bears late in their win over the 49ers in Week 1.

After Montgomery was forced out, Herbert played in 75% of Chicago's offensive snaps and took 100 percent of the snaps in the red-zone. His 27 percent explosive run rate is the best in the NFL so far this season and has the highest rushing EPA per snap of any back. Montgomery's situation will require monitoring, but Herbert has earned a major role with or without him and Gibbs is recommending you spend 20-30% of your FAAB on him if he's available in your league.

Gibbs is also strongly recommending Packers wide receiver Romeo Doubs as a Week 4 waiver wire pickup. Doubs turned in 1,000-yard seasons in each of his last two years at Nevada and finished his four seasons in Reno with 225 receptions for 3,322 yards and 26 touchdowns. The Packers drafted him in the fourth round and he looked like the more productive of Green Bay's two rookie receivers even before Christian Watson suffered a hamstring injury that held him out of last week's game.

With Watson and Sammy Watkins (hamstring) out, Doubs took advantage of increased opportunities by hauling in all eight of the targets sent his way for 73 yards and a touchdown. He ran a route on a season-high 94% of Green Bay's dropbacks in Week 3 and with Watkins out for the year, even if Watson can play there is a high likelihood of Doubs remaining heavily involved in the passing attack moving forward.
