Watch Now: NFL Storylines: Nick Foles Saves Bears in Relief of Mitchell Trubisky (1:07)

More Fantasy football injuries and depth chart changes occurred in Week 3, meaning the Week 4 Fantasy football waiver wire will be extremely busy. 49ers running back Jeff Wilson Jr. was pressed into more action last Sunday and finished as the Fantasy RB10 for the week. Should Wilson be among your prime Week 4 Fantasy football waiver wire picks? Seahawks running back Chris Carson could miss Sunday's game at Miami, and Carlos Hyde is expected to start in his place. Should Hyde be one of your top Week 4 NFL Fantasy football waiver picks?

Which players on Fantasy football waivers are worth grabbing? Before determining who to target, be sure to see what SportsLine's Scott Engel has to say.

Engel is an inaugural member of the Fantasy Sports Writers Association's Hall of Fame. He is a four-time FSWA Award Winner and nine-time finalist, and has pulled off a three-peat in his prestigious New York City Fantasy Football League that includes other experts and high-stakes players. If there's anyone who knows what it takes to win a league, it's him. Engel went 35-10 in his seasonal Fantasy Football leagues in the first three weeks of the season. 

Now, he's revealed the best 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 Engel is advising Fantasy players to target on the Week 4 waiver wire: Bengals rookie wide receiver Tee Higgins. He was elevated into a more prominent role in the Bengals' passing game on Sunday against Philadelphia and responded with the first two touchdown receptions of his pro career. Higgins drew nine targets from Joe Burrow as his role in the Bengals' offense continued to increase. 

Checking in at 6-foot-4, 215 pounds, Higgins provides a big target for Burrow on key passing downs and in potential scoring situations. The Bengals quarterback leads the AFC with 141 passing attempts and will continue to gun the ball frequently, ensuring more playmaking opportunities for Higgins going forward. Fellow wide receivers A.J. Green and Tyler Boyd will command defensive attention, which should help Higgins to get open often.

Another waiver wire target he's all over entering Week 3: Packers tight end Robert Tonyan. While most Fantasy players eyed Jace Sternberger as the Green Bay tight end to target as a deep sleeper in summer drafts, Tonyan was having a strong camp and winning favor internally in Green Bay. His name was rarely mentioned in Fantasy circles, though. 

Tonyan scored in Week 2, and then caught five passes for 50 yards and another TD on Sunday night. He has already emerged as the clear top tight end in Green Bay and has dominated the snap counts at the position for the Packers. He stepped forward to help ease the absence of Davante Adams and may continue to be a worthy Fantasy streamer in the weeks ahead. 

How to set your Week 4 waiver wire claims

Engel is also all-in on an overlooked running back who has massive upside. This player is still widely available and could be a huge boost to your Fantasy football roster moving forward. You can only see who it is at SportsLine
