Colts QB Anthony Richardson still in concussion protocol

Rookie quarterback Anthony Richardson remains in concussion protocol as of Monday afternoon, Indianapolis Colts coach Shane Steichen said.

Richardson and starting center Ryan Kelly, who's also in the protocol, must participate in a non-contact and a contact practice in order to be cleared from the protocol ahead of Week 4's game against the visiting Los Angeles Rams next Sunday.

Steichen does not yet know if Richardson will return when practice resumes Wednesday.

Richardson, the fourth overall pick in April's draft, was named the Colts' No. 1 quarterback during training camp. He suffered the concussion in Week 2 against the Houston Texans.

Gardner Minshew started Week 3 for Indianapolis (2-1) at the Baltimore Ravens and completed 27 of 44 passes for 227 yards and a touchdown in the Colts' 22-19 overtime win.
