Of course, this is all dependent on Sherman actually leaving Northern California without a contract.
But Sherman is also expected to explore the free agent market and he may well have played his last game with the Seahawks. The days of an Achilles tear being an immediate career-ender are long past, but for a cornerback who never had outstanding deep speed-and is less than three weeks from his 30th birthday-it's hard to think he'll be back to top form before the season starts.
Sherman balked at that so the Seahawks instead explored trade options.
Sherman ended last season on injured reserve because of a ruptured right Achilles.
However, Sherman's Achilles injury makes him too much of a risk for the Colts, who aren't necessarily in a "win now" mode.
Sherman made All-Pro four times in seven seasons with the Seahakws, who released him with a failed-physical designation to spare $11 million on their 2018 salary cap.
But Sherman said at the Sports Star awards he thought he would be ready for the beginning of mini-camp.
Asked by Tom Pelissero of the NFL Network on Friday what he wants out of a new team, Sherman said: "Looking for a great fit".
Sherman has had to battle some injuries in recent years, but when healthy, he is still one of the better cornerbacks in the league.
General manager John Lynch recently noted it doesn't take a "savant" to see the 49ers need cornerbacks. The 49ers have over $60 million in salary cap space after re-signing six players this offseason, including Sherman's former Seahawks teammate Cassius Marsh, a defensive end. He can now sign anywhere - including the Seahawks - without having to wait until the start of free agency on March 14.
