Baltimore Ravens QB Lamar Jackson has played well this season. He led the Ravens to a win over the Kansas City Chiefs and against the Detroit Lions in a nail-biter. Lamar Jackson remains a threat on the ground and through the air, despite missing some key receivers. When you are facing a strong defense like the Denver Broncos, you want your star QB to be 100%. However, Lamar Jackson may not be in for Sunday.Is Lamar Jackson playing agains the Denver Broncos in Week 4?Billy Heyen@BillyHeyenLamar Jackson didn’t quite stick the landing on his flip into the end zone 😅11:10 AM · Sep 19, 20214212Lamar Jackson didn’t quite stick the landing on his flip into the end zone 😅 https://t.co/iU1bexPq73The Baltimore Ravens currently have Lamar Jackson listed as questionable with a back/hip injury. He missed practice on Wednesday and Thursday due to soreness. The injury occurred in a manner that will anger any coach in the NFL: celebrating. On a TD run in Week 2, Lamar Jackson flipped into the endzone and apparently landed hard on his back/hip. Celebrating is no longer a flag in the NFL, but that doesn't mean you can get careless with it, especially as a former MVP QB.Lamar Jackson returned to practice on Friday, a step in the right direction. He is expected to play on Sunday, according to head coach John Harbaugh. Lamar Jackson's health has held up quite well over the years as a dual-threat QB, but he surely won't be flipping into the endzone any time soon.Without Lamar Jackson, the Baltimore Ravens wouldn't stand a chance against the Denver Broncos. Denver have eight sacks on the season and have allowed just 26 points and 665 total yards. Granted their opponents are 0-9 on the season, but their defense is still very good.Jamison Hensley@jamisonhensleyRavens first-round pick Rashod Bateman moved around well in his first practice since groin surgery a month ago1:46 AM · Sep 29, 20211914179Ravens first-round pick Rashod Bateman moved around well in his first practice since groin surgery a month ago https://t.co/imDdliW5cnThe good news is that both Rashod Bateman and Myles Boykin have been activated off IR, which will help with the passing game inconsistencies. RB Ty'Son Williams has tapered off a bit, so Jackson's presence should help the run game as well. When it comes to fantasy football, he's the QB9 and should be a QB1 for Week 4 if he is indeed playing. The Ravens have the edge in the spread at -1, which is closer than anticipated. It could end up being a low-scoring game and not come close to the over/under of 44.5 points. When Lamar Jackson is on the field, it's hard to count out Baltimore. The concern is whether he's 100%.Also Read: Who Is Lamar Jackson's Girlfriend?
