One of the biggest offseason acquisitions for the Buffalo Bills may never make it to the regular season, with a new report suggesting that the team’s highest-profile backup could already be on the trade block.

The situation originates in Indianapolis, where Colts quarterback Carson Wentz suffered a foot injury that could keep him out for a significant stretch. Wentz is reportedly visiting a foot specialist and may need surgery, which could keep him out beyond the start of the season. With not much experienced depth behind Wentz in Indianapolis, some believe that the solution could be found in the Buffalo Bills training camp.

As Nick Wojton of USA Today’s Bills Wire noted, backup quarterback Mitch Trubisky could be an attractive option for the Colts if it turns out that Wentz will miss any significant time. Trubisky is among the most experienced of the second-string quarterbacks in the NFL, having come off a stretch as the Chicago Bears starter. Wojton noted that the Bills are unlikely to get a high return, with anything in the first two rounds of the NFL Draft likely off the table.

“What a trade would rely on is if the Colts would potentially be comfortable enough giving up something like fourth-round pick,” he reported. “Such a selection would have decent value and the Bills would be on the hook for a $2 million dead cap hit in trading Trubisky, per Spotrac.”

The Colts traded for Wentz in the offseason after their playoff loss to the Bills and the retirement of veteran starter Philip Rivers.

Trubisky reportedly turned down higher offers to choose Buffalo, with Bills general manager Brandon Beane saying they sold the former No. 2 overall pick on the ability to work with the coaching staff that helped turn Allen into an MVP-caliber player.
