Chargers QB Philip Rivers (concussion) put in a limited practice on Wednesday. The fact that he was out there at all means he's made progress through the protocol. We'll continue to track his progress ahead of Sunday's game against the Bills.

QB Philip Rivers announced his retirement on Wednesday. The 39-year-old played 17 seasons -- 16 with the Chargers, his last with the Colts -- and sits 5th in both career passing yards and TDs. Rivers turned in 10 top-12 fantasy seasons. His retirement leaves Jacob Eason as the only QB on the roster signed for 2021. We'll see if the Colts bring back QB Jacoby Brissett, but they'll certainly be adding to the position via free agency and/or the draft.

Colts QB Philip Rivers will likely need offseason surgery to repair a ruptured plantar plate, according to NFL Network's Ian Rapoport. It's basically a more severe version of turf toe that Rivers is dealing with. He played through the issue last week, throwing for 295 yards, 2 TDs and 1 INT in the loss to the Titans. The injury adds some risk to Rivers' fantasy profile, but he's still a spot-start option today vs. a bad Texans defense.

The Colts have reached agreement with QB Philip Rivers on a 1-year deal, according to ESPN's Adam Schefter. It's been a long-anticipated move that should upgrade the QB play for Indy. Of course, Rivers is 38 and coming off 1 of his worst seasons -- both of which surely factor into the Chargers letting him go. Rivers over Jacoby Brissett should help WR T.Y. Hilton and TE Jack Doyle, but we're not sure about him leading an enormous rebound for the Colts offense on whole. Over the past 4 years, Indy has ranked top 10 in scoring and yards in the 2 seasons Andrew Luck has played; 25th or worse in yards and 16th or worse in scoring in the 2 years Luck missed. Colts HC Frank Reich does have experience with Rivers, coordinating his Chargers offense in 2014 and 2015, and spending 2013 as the QBs coach. San Diego finished 2014 ranked 17th in scoring and 18th in yards; 2015 found the Chargers 9th in yards but just 26th in points.

The Chargers have "moved on" from QB Philip Rivers, according to Fox Sports' Jay Glazer. Rivers has spent the past 16 seasons with the franchise after being traded from the Giants during the 2004 draft. The 38-year-old reportedly wants to continue playing, so we'll see who he draws interest from in free agency. The Chargers, meanwhile, are now obviously a candidate to take a QB in the 1st round of April's draft. They currently hold the 6th overall pick.

Chargers QB Philip Rivers tossed 7 INTs over his past 2 games before the Week 12 bye. According to NFL Network's Ian Rapoport, another similar game could get him benched in favor of Tyrod Taylor. "It is a move the Chargers hope to not think about and hope to not make," Rapoport writes. But "it would be made, if necessary." Rivers sits well down our QB rankings for today's game at Denver. The next 3 contests find the Chargers visiting Jacksonville and then hosting Minnesota and Oakland, though. There's big passing upside in at least those Week 15 and Week 16 matchups ... for whoever's quarterbacking the Chargers.
