Colts Sign Charlie Heck After Quenton Nelson Trade: Fantasy Impact
Updated Oct. 29, 2026, at 1:06 p.m. CT. The Indianapolis Colts signed veteran tackle Charlie Heck to the 53-man roster Thursday, added guard Joshua Gray to the practice squad and released linebacker Germaine Pratt from the practice squad.
The timing is important. Indianapolis traded All-Pro left guard Quenton Nelson to Seattle earlier this week, leaving the offensive line in transition before Sunday’s road game against Jacksonville. Heck adds experienced tackle depth, but he is not a direct one-for-one Nelson replacement. Gray is the new guard addition, and the Colts have not announced their Week 8 starting left guard.

What Charlie Heck adds to Indianapolis
Heck is a 6-foot-8, 311-pound veteran with 67 regular-season appearances and 29 starts across Houston, Arizona, San Francisco, Tampa Bay and Miami. The Texans selected him in the fourth round of the 2020 NFL Draft, and his experience gives Indianapolis a more established emergency option at either tackle spot than a typical midseason signing.
That distinction matters. The Colts’ Tuesday unofficial depth chart listed Bernhard Raimann at left tackle, Jalen Travis at right tackle, Luke Tenuta as the reserve right tackle and Dalton Tucker behind Nelson at left guard. The chart was released before Nelson’s departure and before Heck signed, so it no longer answers the most important lineup question.
Joshua Gray is the guard addition to watch
Gray is initially joining the practice squad, not the active roster. The 6-foot-5, 299-pound lineman started a school-record 56 games at Oregon State and spent time with Minnesota’s practice squad earlier this season after previous stops with Atlanta and Carolina.
His résumé gives the Colts developmental guard depth, but the practice-squad placement should prevent fantasy managers from assuming Gray will replace Nelson immediately. Dalton Tucker was the listed backup at left guard before the trade, while Matt Goncalves and rookie Jalen Farmer were listed at right guard. Indianapolis could also adjust positions once the coaching staff evaluates its full group.

Jonathan Taylor fantasy football impact
Taylor remains an automatic fantasy start. He leads the NFL with eight rushing touchdowns, ranks sixth with 765 yards from scrimmage and is tied for second with 157 touches. His workload and scoring role are strong enough to keep him in the RB1 tier even while the line changes around him.
The reasonable concern is efficiency. Nelson’s departure removes an elite interior blocker, and Thursday’s transactions do not establish a settled replacement plan. If Indianapolis rotates at left guard or changes multiple positions, Taylor could encounter more early contact and fewer clean interior lanes.
Fantasy recommendation
Jonathan Taylor: Start as an RB1. Do not bench elite volume because of one offensive-line change.
Colts passing game: Keep normal rankings, but monitor the announced starting five for protection continuity.
Jaguars D/ST: The line uncertainty is a modest positive, not enough by itself to force Jacksonville into every lineup.
Charlie Heck and Joshua Gray: No direct fantasy value; their relevance is through protection and rushing efficiency.
Taylor’s Thursday comments also matter. He said he has not requested a trade and has not heard that one is imminent. He remains under contract beyond 2026, unlike Nelson and defensive tackle DeForest Buckner, who were nearing free agency. That does not make a future deal impossible, but fantasy managers should not treat speculation as a transaction.

Fantasy scoring assumptions
Football Nation’s recommendation uses half PPR scoring: one point per reception, one point per 10 rushing or receiving yards and six points per rushing or receiving touchdown. Taylor remains an RB1 under that framework because his 157 touches and eight rushing touchdowns create both volume and scoring paths. Jaguars D/ST guidance assumes common team defense scoring and should be adjusted for league specific bonuses and yardage penalties.
The strongest counterargument
The strongest case against the confident Taylor ranking is that Nelson’s departure could materially reduce interior run efficiency before Indianapolis settles on a replacement. Thursday’s moves add depth, but Heck is a tackle and Gray is on the practice squad, so neither transaction proves the left guard problem is solved. The answer is not to bench Taylor’s elite workload. It is to lower his efficiency expectation and monitor the announced starting five before kickoff.
What the Pratt release means
Pratt’s release is notable because of his experience—113 career games, 104 starts and 737 tackles—but he was on the practice squad rather than the active roster. The move does not create an automatic Week 8 linebacker change. It primarily opens a practice-squad spot while Indianapolis redistributes resources around a roster that has already traded two veteran leaders.
Week 8 checkpoints
Watch for an updated Colts depth chart or coach announcement naming the starting left guard.
Check whether Heck practices at left tackle, right tackle or both.
Do not assume Gray will be elevated from the practice squad without an official transaction.
Recheck the Friday injury report and Sunday inactive list before setting Jaguars D/ST or Colts fringe starters.
Bottom line
Heck gives Indianapolis proven tackle insurance, and Gray adds a developmental guard option after the Nelson trade. Neither move confirms who will start at left guard against Jacksonville. Taylor remains a must-start RB1 because of his league-leading touchdown production and elite workload, but the Colts’ new offensive-line combination is a legitimate efficiency variable to monitor.
