Indianapolis Colts quarterback Anthony Richardson will not play in Sunday's game against the Baltimore Ravens as he remains in the concussion protocol.
Richardson has not practiced this week after self-reporting a concussion in the second quarter of Sunday's win over the Houston Texans.
With Richardson out, Gardner Minshew will make his first start for the Colts.
A source told ESPN's Jeremy Fowler that Richardson is optimistic about playing in Week 4 against the Los Angeles Rams, assuming he passes through the protocol. The Colts and Richardson have been cautious this week in their discussions about his return.
