After missing three weeks of practice, starting cornerback Marlon Humphrey returned to the field with his Ravens teammates Wednesday.

The three-time Pro Bowler initially suffered a calf injury in Week 10 against the Cleveland Browns. Humphrey returned for the Week 14 game against the Los Angeles Rams but reinjured himself three games later.

Humphrey, who was limited Wednesday, had not participated in practice since he was injured Dec. 31 against the Miami Dolphins. He missed practices for the final week of the season, the bye week and the lead-up to the divisional-round game against the Houston Texans. But things are looking up for the AFC championship game at M&T Bank Stadium on Sunday.

As the Ravens prepare to host the Kansas City Chiefs and superstar quarterback Patrick Mahomes, any help is welcome, especially from their top cornerback.

If Humphrey can play, he will, coach John Harbaugh said Monday. If he can’t, the Ravens have confidence in the other cornerbacks, he said.

Brandon Stephens has played well all year. Ronald Darby was Humphrey’s primary replacement against the Texans last week. Harbaugh also gave shout-outs to Rock Ya-Sin and Arthur Maulet.

While the Chiefs’ receiving corps doesn’t have the elite downfield speed of Tyreek Hill, Mahomes still has tight end Travis Kelce and rookie wide receiver Rashee Rice as weapons. And Mahomes’ elusiveness helps him make plays out of nothing.

Inside linebacker Del’Shawn Phillips, who injured his shoulder against the Pittsburgh Steelers in Week 18, returned to practice as a limited participant. Ya-Sin (knee) was limited, too.

However, the Ravens’ offensive line was missing starting right guard Kevin Zeitler, who took the day off to rest. He injured his knee/quadriceps against the San Francisco 49ers on Dec. 25 and missed the final two games of the season. He returned to practice Jan. 10 and played 90% of the Ravens’ game against Houston.

Tight end Mark Andrews, who continues to progress in his recovery from midseason ankle surgery, was a full participant for his third straight practice. Wide receiver and returner Tylan Wallace, who injured his knee at practice during the bye week, was absent.

Six Chiefs missed practice: starting left guard Joe Thuney (pectoral), starting right guard Trey Smith (illness), starting running back Isiah Pacheco (ankle/toe), rotational wide receiver Skyy Moore (knee) starting defensive tackle Derrick Nnadi (triceps) and starting safety Mike Edwards (concussion). Pacheco told local reporters he plans to play Sunday. Moore has not been activated off injured reserve.

Starting linebacker Willie Gay (neck) and starting cornerback L’Jarius Sneed (calf) were limited, along with backup quarterback Blaine Gabbert.
