Marcus Mariota Starts in London and Terry McLaurin's Hamstring Is the Colts-Commanders Swing Factor

Marcus Mariota will start for the Washington Commanders against the Indianapolis Colts at Tottenham Hotspur Stadium on Sunday (9:30 a.m. ET, NFL Network), after Dan Quinn ruled out Jayden Daniels on Friday with his left elbow injury. The bigger late development sits on the receiver line: Terry McLaurin is questionable with a hamstring injury he picked up in practice. Both teams are 1-2 and both got their first win in Week 3, so the London game is a genuine swing spot for two clubs trying to avoid falling two games under .500.

The market has Indianapolis as a 3.5-point favorite at most books (4 at some), with the total sitting between 47.5 and 48.5 depending on the shop. Daniels' ruling did not move the number in a meaningful way, which tells you the market had already priced in Mariota.

How both teams got here

Indianapolis snapped a nine-game losing streak with a 19-17 win over Houston, and it was not pretty. Daniel Jones completed 24 of 36 passes for 235 yards with one touchdown and one interception, and he fumbled three times, losing two. His season QBR sits at 48.5, a lackluster number for a quarterback the Colts need to carry a thin receiver room with Alec Pierce on injured reserve.

Washington's win was louder. Mariota went 19 of 31 for 183 yards and three touchdowns without a turnover in a 33-31 upset of Seattle, and the league named him a FedEx Air and Ground Player of the Week for it. That was a backup quarterback beating a contender with efficiency rather than volume, and it is the template Washington will try to repeat in London.

The final injury report

The Commanders carry the longer list. The Colts did not rule out anyone.

Washington did get good news on linebacker Frankie Luvu (groin) and tight end Chig Okonkwo (hamstring), who were both cleared. McLaurin was limited Friday, and reports out of London say he is still expected to play against the Colts. Allen did not practice Friday, so his status is the one to track on the Indianapolis side before the early lock.

Fantasy fallout: Indianapolis

Josh Downs is the receiver to want. With Pierce out, Downs drew a team-high 10 targets in Week 3 and has a 30% target share over the last two weeks with 111 air yards per game. If Allen sits, Downs' share only grows. Washington's pass defense ranks bottom-four in passing efficiency, success rate and completion percentage over expected allowed, per one weekly matchup breakdown, which makes Downs a confident WR2 in PPR.

Tyler Warren caught 9 of 10 targets for 55 yards against Houston. The volume is elite for a tight end, but his average depth of target in that game was 1.9 yards, second-lowest among all receivers and tight ends with at least 10 targets. That is a high-floor, low-ceiling profile. He stays a weekly starter at a thin position; just do not expect long gains without a scheme change.

Jonathan Taylor is the frustrating one. Houston held him to 68 yards on 23 carries, plus two catches for four yards on three targets. He was limited in practice this week but was not given a game designation on Friday. The volume makes him an RB1 in a game the Colts are favored to win, and late-game carries while protecting a lead are his path to a bigger day.

Daniel Jones is a fringe QB2. The turnover issues are real, and three fumbles in one game is not a fluke you can ignore, but he faces a secondary that has struggled and he has two strong underneath targets.

Fantasy fallout: Washington

Stefon Diggs has 13 catches for 135 yards and three touchdowns on 22 targets, with at least four catches in every game. He has run a team-high 44 routes from the slot, and Colts nickel corner Justin Walley has allowed 13 catches on 15 slot targets for 213 yards and two touchdowns. That is the single best matchup on the Washington side, and it gets better if McLaurin is limited or leaves early. Start Diggs as a WR2.

Terry McLaurin is a riskier play than usual. A questionable tag for a hamstring injury suffered during the week is a real yellow flag, because soft-tissue injuries are the ones that tend to cost snaps in-game. He is a WR3 with downside this week; managers with a comparable option in a later window should consider it.

Marcus Mariota is a streaming QB2 with upside in one-quarterback leagues. The Colts defense allows a league-worst 417.3 yards per game, and Mariota adds rushing value on top of his passing. His Week 3 line came with only 11 rushing yards, but scrambles can be a weekly floor for him.

The backfield is muddy. Jacory Croskey-Merritt ran 19 times for 36 yards against Seattle and had a 48-yard touchdown erased by an illegal formation penalty. With White out, Croskey-Merritt is the lead back, but Washington brought newly re-signed Austin Ekeler to London and he may suit up right away. Treat Croskey-Merritt as a volume-based RB3 and keep Ekeler on benches until a role shows up.

Betting angle

The spread is the tighter read. Indianapolis is laying 3.5 with a quarterback who has turned the ball over too often, against a Washington team that just won a shootout with its backup. The Colts' edge is their defense against a Mariota offense that is efficient but not explosive, plus a Washington offensive line that will be without guard Sam Cosmi.

On the total, both defenses have given up yards, and the Colts' 417.3 yards allowed per game is the number over bettors will point to. The concern is that Mariota's Week 3 game was more efficiency than volume (183 passing yards), and a Taylor-heavy Colts game plan shortens the game. Totals in this range ask for both offenses to contribute. The early kickoff and international travel add a variable that is hard to quantify either way.

For prop-minded readers, the Diggs slot matchup and Downs' target share are the two cleanest usage stories in this game. The Verdexed model's pick for Colts at Commanders, and the rest of the slate, is at /blog/nfl-week-4-picks-2026, with win probabilities on /nfl/predictions.

What's next

The decisions come early. With a 9:30 a.m. ET kickoff, inactive lists land well before the main slate, so check McLaurin and Allen first thing Sunday morning and set lineups around the answer. If McLaurin is out, Diggs moves into WR2 territory with a higher floor, and Washington's secondary receivers get a target bump. If Allen is out, Downs and Warren absorb the targets.

Washington's bye arrives in Week 7, so Commanders players are available for two more weeks after London. Daniels' elbow remains the longer storyline: every week Mariota wins, the urgency to rush Daniels back drops, and Mariota's fantasy value as a streamer holds steady. The Colts are not on bye until Week 13, so Downs and Warren hold their week-to-week value through the middle of the season.
