Sunday Night Football in Week 7 features the Indianapolis Colts and the San Francisco 49ers going toe-to-toe trying to salvage anything from their injury-detailed seasons.Since their run to the Super Bowl two seasons ago, the 49ers' roster has been decimated by injuries to their star players, with quarterback Jimmy Garoppolo being one of the biggest victims of the injury bug. The team picked quarterback Trey Lance in the first round of the 2021 NFL Draft and he too is hurt right now and won't be available for this game.The Colts took a gamble on former Philadelphia Eagles quarterback Carson Wentz after his relationship with his former team quickly deteriorated. Wentz is injury-prone, but he managed to stay healthy last year and has not missed a game this season. The problem for Indianapolis is that, while the quarterback is healthy, other important players aren't.PFF Fantasy Football@PFF_FantasyCarson Wentz has a 147.8 passer rating on throws 10+ yards downfield1st in the NFL 🚀8:01 PM · Oct 19, 20211178149Carson Wentz has a 147.8 passer rating on throws 10+ yards downfield1st in the NFL 🚀 https://t.co/2mPQT0O3PpCheck out the injury report and the starting lineup for this Colts-49ers Week 7 matchup.Indianapolis Colts vs. San Francisco 49ers injury reportIndianapolis ColtsPlayerPositionInjuryGameT.Y.
