The Houston Texans will be missing a lot of firepower when they visit the Cleveland Browns on Sunday.

All-Pro defensive end Danielle Hunter is out with a hamstring injury. Pro Bowl linebacker Azeez Al-Shaair is out with a groin injury. On Saturday running back David Montgomery joined them on the list.

Receiver Marvin Harrison Jr. and rookie guard Keylan Rutledge have also been ruled out.

Big holes on defense

Hunter has four sacks this season, which is tied for second on the team. He was limited in practice Thursday and did not practice Friday.

Al-Shaair leads the Texans with 68 tackles and wears the green dot as the defensive play caller. He has dealt with the groin injury since Week 3 against the Indianapolis Colts and missed the Week 4 game against the Dallas Cowboys.

Fellow edge rusher Will Anderson Jr. was listed as questionable on Friday with an ankle injury. Like Hunter, he was limited Thursday and did not practice Friday.

Montgomery stays home

Montgomery was listed as questionable on Friday. On Saturday the team said he will not travel to Cleveland.

It will be the fourth straight game he misses. He hurt his groin against the Tennessee Titans and has not played since Week 5, though he did practice this week.

Other moves

Harrison was recently acquired by Houston. He has six catches for 60 yards and a touchdown in three games with the Texans.

Tight end Brevin Jordan is also out. Cornerback Jaylin Smith will not be activated from injured reserve.

Linebacker Jake Hummel was activated from injured reserve. He has been out since Week 1 with a groin injury. The Texans also elevated linebacker Chad Muma and running back Dare Ogunbowale from the practice squad.

Some good news

Safety Reed Blankenship, receiver Tank Dell, tackle Blake Fisher, defensive tackle Tommy Togiai and running back Woody Marks are all off the injury report and set to play.
