Ravens cornerback Marlon Humphrey said after practice Thursday that his injured calf was “doing good” ahead of Sunday’s AFC championship game against the Kansas City Chiefs.

Humphrey, a limited participant in his return to practice Wednesday and again Thursday, hasn’t played since leaving the Ravens’ Week 17 win over the Miami Dolphins. He deferred to coach John Harbaugh when asked how his availability will be evaluated but acknowledged that his absence has been “rough.”

“I’ve been kind of trying to stay positive through it. It’s definitely not been ideal for me,” he said. “But ... honestly, what’s helped me get through it the most is just seeing how the guys are playing on Sundays. I mean, I obviously watch the defense a little closer than the offense because I know what’s going on with the defense, but the way those guys have been flying around, it’s really been inspiring to see that you can have the comfortability to just shoot your shot.”

Right guard Kevin Zeitler and wide receiver Tylan Wallace returned to practice Thursday, giving the team nearly full attendance.

Zeitler missed practice Wednesday for a rest day, though he’s also dealt with knee and quadriceps injuries in recent weeks. Wallace, who was limited Thursday, had been sidelined for nearly two weeks by a knee injury.

Only one player on the Ravens’ 53-man roster, cornerback Rock Ya-Sin, was absent. He was limited by a knee injury Wednesday and sidelined Thursday.

Tight end Mark Andrews (ankle), who has yet to be activated off injured reserve, practiced for the sixth straight day. He has been a full participant in four straight workouts and appears likely to return for Sunday’s game.

Three potential Chiefs starters missed practice for the second straight day: All-Pro left guard Joe Thuney (pectoral), wide receiver Skyy Moore (knee) and running back Isiah Pacheco (ankle/toe). Moore is on injured reserve, and Pacheco told local reporters he expects to play Sunday.

Four potential Kansas City starters were limited: wide receiver Kadarius Toney (hip), linebacker Willie Gay (neck), cornerback L’Jarius Sneed (calf) and safety Mike Edwards (concussion).
