No charges have been filed against Reed, but police did seize evidence from his apartment that's being analyzed. He could face charges at a later date once that evidence is examined, according to police officials.
"He'll play," Harbaugh said Saturday at the Ravens' training complex. "It's not something that really affects his football status at this time. He'll have a chance to tell his side of it in the proper way when the time comes.
"We have to see how it all shakes out. It's in other people's hands right now and I think time will kind of work that out as we go."
Reed practiced Saturday and will return kickoffs Monday night. He returned an 84-yarder against the Carolina Panthers last month.
Baltimore County police raided the fifth-round draft pick's apartment in Owings Mills after receiving a call about potential narcotic activity, according to police.
"Currently, he hasn't been charged with anything," Baltimore County police spokesman Robert McCullough said. "Evidence has been seized and is being analyzed. Any charges are pending further investigation."
Reed has declined to discuss the case.
"I'm good," Reed told the Carroll County Times. "I ain't got nothing to say right now."
HEAP RULED OUT: Tight end Todd Heap was ruled out due to a pulled right hamstring suffered against the Pittsburgh Steelers.
Harbaugh had expressed hope earlier Saturday that Heap might be able to play.
"I think he's got an outside chance, I would say," Harbaugh said. "Realistically, it will probably be tough for him to get back. I'll hold out hope, as always, because he's a tough guy.
"He's been rehabbing like crazy. We made a lot of progress from yesterday to today, but we'll probably plan for the worst and hope for the best."
Rookie Ed Dickson is preparing to start in place of Heap. It will be the first start of his NFL career for the third-round draft pick from Oregon.
"It's been a great week of preparation," Dickson said. "I'm not going to try to do anything major. I'm going to do my job, and that's all they asked of me. I'm just excited and ready to get after it. After a loss like that, I'm ready to get back at it and get another victory."
Dickson has caught eight passes for 112 yards this season, including a 58-yard reception against the Denver Broncos.
"I feel really comfortable," Dickson said. "The biggest problem is getting that chemistry down with me and Joe Flacco. We started a couple days after practice to work on the things we needed to work on, and if
I'm up this Monday night, I'm just going to do my job and try and get the victory."
At 6-foot-4, 245 pounds, Dickson is an extremely athletic downfield target.
He's Oregon's all-time leader for tight ends for receptions and receiving yards with 124 receptions for 1,557 yards and 12 touchdowns.
The Ravens plan to scale back the offense a bit with Dickson starting. Dickson isn't an experienced blocker.
Fellow rookie Dennis Pitta will also have an expanded role.
"There's probably some subtle changes," Harbaugh said. "You might not do as much with Ed as you would do with Todd. He's really an accomplished player. He can do so many things. He's very versatile.
"Ed is in his first year, so I think we have to keep that in mind. Ed is capable of doing some things that are special. He's fast, he's athletic, he'll get in there and fight you blocking, so we've got a lot of confidence in he and Dennis."
WASHINGTON A GAME-TIME DECISION: Cornerback Fabian Washington is questionable with a strained left hamstring and said he'll be a game-time decision.
He injured his leg during practice Thursday.
"It will be close," Washington said. "We've been staying on top of it all week."
Pro Bowl fullback Le'Ron McClain is probable as well as cornerback Lardarius Webb (thigh), safety Tom Zbikowski (bruised heel).
For the Texans, tight end Garrett Graham (hamstring) is out.
Wide receiver Andre Johnson (high ankle sprain), defensive end Mario Williams (sports hernia) returned to practice on a limited basis, quarterback Matt Schaub (knee), offensive tackle Eric Winston (shoulder), offensive guard Mike Brisiel (shoulder), cornerback Glover Quin (hand), outside linebacker Brian Cushing (knee), linebacker Xavier Adibi (hamstring) and tight ends Owen Daniels (hamstring and Joel Dreessen (ribs) are all probable.
EXPANDED ROLE: Veteran wide receiver Donte' Stallworth generated the Ravens' longest play from scrimmage this season against the Pittsburgh Steelers.
He caught a 67-yard pass that quarterback Joe Flacco short-armed.
"The corner must have thought it was going to Ed Dickson and it kind of went over his head and Joe made a safe throw," Stallworth said. "We had an easy completion. It was a smart thing to do. We were able to get down the field and change field position.
With his speed, the Ravens would like to get Stallworth more involved.
He has two receptions for 82 yards this season and four runs for 30 yards.
"Yeah, I think that's something we've been working towards, just trying to get some balls down the field," Stallworth said. "Hopefully, that role could be expanded during games. With Todd being out, my role may need to be expanded in new ways. Whatever comes my way, I'll be ready for it."
Stallworth has played at Reliant Stadium before.
Back in 2006 with the New Orleans Saints, Stallworth caught six passes for 141 yards and a touchdown at Houston.
"I like playing there," Stallworth said. "It's a very fast surface."
QUICK HITS: Harbaugh said the Ravens had a sharp week of practice after an emotional loss to the Steelers. "I thought we had an excellent week of practice," he said. "One thing about our guys: they're professionals. I heard a couple guys say it: It's a tough loss, and I think everybody has a tough time getting over it: fans, coaches, players. You know it means a lot to all of us. The Ravens mean a lot to all of us, but we've got to bounce back and go to the next week and we've got to start focusing on the next team, and as players and coaches, you really don't have until the next game to do that. You have to do it the next day. And I thought our guys did a good job of that."
… Harbaugh said it didn't matter to him if Reliant Stadium's retractable roof is open or closed. "Probably not," he said. "It just depends how cold it is. I think they have a policy down there, 50 to 80 degrees, they try to leave it open. We'll just have to see."
