The Ravens could be in danger of not having two key starters for Sunday’s showdown against the AFC North rival Browns in Cleveland.

Wide receiver Zay Flowers (ankle) and cornerback Marlon Humphrey (knee) did not practice for a second straight day Thursday in Owings Mills.

Flowers is the Ravens’ leading receiver with 34 catches for 412 yards and a touchdown, while Humphrey’s four interceptions lead the team and are a career high. Both were injured during Baltimore’s 41-31 win Monday night over the Tampa Bay Buccaneers.

They are hardly the only concerns Baltimore is dealing with.

Also absent for a second straight day were reserve rookie running back Rasheen Ali (ankle) and rookie cornerback T.J. Tampa (ankle). If Humphrey, Ali and Tampa can’t play, that would likely mean activating cornerback Jalyn Armour-Davis (hamstring), who began practicing earlier this week after being on injured reserve and was a full participant Thursday after being limited a day earlier.

Meanwhile, defensive tackle Travis Jones was limited after not practicing Wednesday, but he was wearing a substantial wrap/brace on his injured left ankle and was struggling to move around during the open portion of practice.

Three others — linebacker Malik Harrison (groin), defensive tackle Broderick Washington (knee) and cornerback Nate Wiggins (shoulder/illness) — were all full participants after being limited or not practicing a day earlier. Cornerback Arthur Maulet (hamstring) also fully practiced for the first time and is eager to return to the field to help what has been a beleaguered secondary.

“Feels good,” Maulet said. “I’m ready to play.

“It was tough obviously because I know I can help the guys. I’m big on communicating … helping guys get aligned and confirming formations and all those type of things. It’s nothing major that they have to work on. It’s just communication. We’ll be fine.”

For the Browns, center Ethan Pocic (knee) and defensive lineman Quinton Jefferson (personal) both returned, though Pocic was limited. Also limited were right guard Wyatt Teller (knee), right tackle Jack Conklin (knee) and backup cornerback Tony Brown (ankle).

Running back Jerome Ford (hamstring), safety Ronnie Hickman (ankle), linebacker Jordan Hicks (elbow/triceps) and left tackle Jedrick Wills (knee) all did not practice for the second day in a row.
