OWINGS MILLS — The Ravens should have most of their key players available for the Monday night game against the San Francisco 49ers.

However, their depth could be tested.

Cornerbacks Arthur Maulet (knee) and Jalyn Armour-Davis (concussion) have been ruled out. Those two players are contributors on special teams and can provide support in the secondary.

Veteran cornerback Rock Ya-Sin could play a bigger role.

In addition, defensive back Damarion “Pepe” Williams is available after missing the previous 14 games because of two offseason ankle surgeries. Last season as a rookie, Williams played in 14 games on defense and special teams, finishing with 22 tackles and two pass breakups.

Wide receiver Zay Flowers has been listed as questionable with a foot injury. However, Flowers appears to be on the mend.  He didn’t practice on Wednesday, was limited on Thursday but was a full participant on Friday.

Flowers leads the Ravens in receptions (65) and receiving yards (680) with three touchdowns.

The 49ers will be shorthanded on the defensive line, which could help the Ravens’ rushing attack.

Defensive tackle Arik Armstead (foot/knee), who has 27 tackles and five sacks, has been ruled out. Fellow defensive tackle Javon Hargrave (40 tackles and six sacks) is listed as questionable with a hamstring injury.

San Francisco also ruled out wide receiver Jauan Jennings (concussion), linebacker Oren Burks (knee), and tight end Ross Dwelley (ankle). Running back Elijah Mitchell (knee) is questionable.
