OCTOTBER 18: Head coach Shane Steichen confirmed on Friday Richardson will indeed suit up on Sunday. Taylor’s ankle injury will cost him a third straight game, so plenty of rushing responsibilities could rest on the second-year quarterback immediately upon returning to action.
OCTOBER 17: Joe Flacco has handled starting quarterback duties for the Colts over the past two games. That will likely change in Week 7, however.

Anthony Richardson is expected to return to action this week, Cameron Wolfe of NFL Network reports (video link). Last year’s No. 4 pick suffered his most recent injury in Week 4, prompting Flacco to take over in his place. The 39-year-old helped lead the Colts to wins in two out of his three appearances, but as Wolfe notes the team’s intention is to return Richardson to the lineup at the first opportunity to do so.
An oblique injury has kept the 22-year-old out of action recently, marking another interruption in his NFL development. Known to be a raw prospect coming out of college, Richardson immediately handled first-team duties during his rookie season. That campaign was cut short by shoulder surgery, and further missed time is the situation team and player obviously wanted to avoid. If he can remain healthy moving forward, though, a Year 2 jump in production could again be possible.
Sitting at 3-3 on the year, the Colts sit mid-pack in a number of offensive categories this year (although they rank last in time of possession). A healthy Richardson could help in several areas, and his mobility will be key to the team’s rushing attack. That will especially remain true if running back Jonathan Taylor is forced to sit out once again in Week 7. Taylor was absent from practice yesterday and again today, casting doubt on the status of his ankle rehab.
Richardson, by contrast, has been a full practice participant over each of the past two days. Barring any setbacks, therefore, he should be in action against the Dolphins on Sunday. It will be interesting to see how effective the Florida product is upon return and whether or not he will be able to avoid any further setbacks on the injury front for the remainder of the campaign.
