The Ravens’ secondary could be missing two starters on Sunday against the Cleveland Browns.

Marlon Humphrey is questionable The Ravens announced Saturday that fellow cornerback Nate Wiggins was not traveling with the team on the flight to Cleveland after missing a week of practice with a knee injury. The first-round pick is considered questionable, which means he isn’t ruled out.

Wiggins missed the Ravens’ practice on Wednesday with a shoulder injury, participated fully in Thursday’s practice but was limited on Friday due to an illness.

The Ravens received reinforcements this week with the addition of cornerbacks Arthur Maulet and Jalyn Armour-Davis. Maulet, who played in 14 matches last year, is making his first appearance of the season after having arthroscopic knee surgery in August. Special teams player Armour-Davis, who split time with Wiggins at the beginning of the season, returns after missing four games with a hamstring injury.

To make room for Armour-Davis on the 53-man roster, the Ravens placed rookie cornerback TJ Tampa (ankle) on injured reserve, meaning he will miss at least the team’s next four games. The fourth-round pick has played just eight defensive snaps this season.

The Ravens also signed undrafted rookie cornerback Bump Cooper Jr. off the practice squad for the first time in Sunday’s game. Starting outside corner Brandon Stephens and backup safety Ar’Darius Washington are also at corner for defensive coordinator Zach Orr.

The Ravens rank last in the NFL in pass defense (287.1 yards allowed per game), but Cleveland had one of the NFL’s worst offenses under starting quarterback Deshaun Watson, who suffered an Achilles tendon injury last weekend. Backup Jameis Winston starts Sunday.
