Week 4 of fantasy football kicked off when the Dallas Cowboys travelled to the Big Apple to take on the New York Giants on Thursday Night Football. Rico Dowdle and CeeDee Lamb came up big to start the week, handing the Cowboys a 20-15 win over the Giants. But there's a lot more action to come and here's everything you need to know about your wide receivers before setting your lineups for Sunday.Week 4 Fantasy Football WRs injuries trackerSyndication: The Indianapolis Star - Source: Imagn1] Tank Dell and Nico Collins injury updatesIt's not looking good for either Dell or Collins in the buildup to Week 4. Dell popped up on the Texans' injury report with a chest injury and did not practice on Wednesday or Thursday. It remains to be seen if he gets on the field on Friday but his counterpart Nico Collins was a limited participant on Thursday with a hamstring injury.2] DeVonta Smith and A.J. Brown injury updatesLike the Texans, the Eagles find themselves in a tough spot. While the Texans still have Stefon Diggs to call upon, the Eagles will have to turn to Jahan Dotson and hope Saquon Barkley pulls off yet another dominant game this week against the Tampa Bay Buccaneers. Smith is currently dealing with a concussion and did not practice on Wednesday and Thursday, making it unlikely that he sees the field this Sunday. Brown, meanwhile, is still dealing with a hamstring injury that kept him out of Week 3 and was also DNP on both days.3] Ja'Marr Chase injury updateThis one was a surprise name to pop up on the Bengals' injury report last night. He was a limited participant on Wednesday night, which raised some concern given the Bengals are 0-3. However, Chase was a full participant on Thursday and is expected to be fit for Sunday's game against the Panthers.4] Justin Jefferson injury updateStar wideout Justin Jefferson was suffering from a quad injury in Week 3, however, he was not listed on the Vikings' injury report for Week 4. He is expected to be a full go when Minnesota takes on Green Bay on Sunday afternoon.5] Diontae Johnson injury updateWideout Diontae Johnson was a late addition to the Panthers injury report with a groin injury. He did not practice on Thursday which means he is a major doubt to face the Bengals.6] Deebo Samuel injury updateSamuel was a limited participant on Thursday with a calf injury and did not practice the day prior. The Niners face the Patriots this week so they can afford to rest their WR1 for Week 5 against the Cardinals.7] Cooper Kupp injury updateThere's a minor update on Kupp in that he is not in a cast anymore. The Rams stopped short of placing Kupp on Injured Reserve with Puka Nacua already on that list. However, Kupp will not suit up for Week 4 against the Chicago Bears.
