With Bernardo Harris suffering a broken left fibula Monday and being out four to six weeks and starter Ed Hartwell excused Tuesday with a tight back, Scott's role has increased.
"I learned to always be ready because it's a physical game and you never know when a guy can go down," Scott said. "You always have to hold yourself accountable.
"My head was swimming as a rookie. I had things floating through my head. You can only get so much of it on the board without actual reps, actual games."
While Ravens coach Brian Billick said the team will investigate signing another linebacker, for now it's Scott's show to share.
"It should heighten the learning curve for him," Billick said.
Last season, Scott appeared in 16 games and tied for the team lead with 17 special teams tackles. He also had a key interception in a 13-12 victory over the Tennessee Titans, snaring quarterback Steve McNair's pass in the end zone.
"With one year seasoning, it's not as shocking as it was last year," Scott said. "I'm more comfortable going out there and confident in what I know."
Undrafted rookie linebacker Chris Brown's repetitions have increased, too.
All of a sudden, he's running with the second defense after making several solid tackles since camp began.
"The main thing is I'm going up," Brown said, "not going downward."
MEDICAL UPDATE: The Ravens' list of injuries is multiplying.
Besides Harris, there are: receiver Javin Hunter (ruptured Achilles' tendon, out for the season); safety Ray Perryman (dislocated left shoulder, out indefinitely) and center Mike Flynn (arthroscopic knee surgery, 2-4 weeks).
Listed as day-to-day: tight end Todd Heap (back); Hartwell (back); offensive tackle Orlando Brown (thigh), return specialist Lamont Brightful (hyperextended knee); cornerback Tom Knight (thumb) and running back Musa Smith (knee).
"I'm always concerned about injuries and how it affects your sequencing," Billick said. "Fortunately, with a few exceptions, they're not real serious, but you've got to be prudent about it because we've got a month until the opener.
Hartwell said he expects to play against the Buffalo Bills in the preseason opener on Saturday after experiencing tightness in his lower back.
Smith still has swelling in his knee that inhibits his ability to cut.
The Ravens switched his anti-inflammatory medicine to something stronger.
"There hasn't been any talk of draining it just yet," Smith said. "They've switched my meds and I'm just icing it and keep on working it out."
QUICK HITS: Before camp began, offensive line coach Jim Colletto said right guard Bennie Anderson needed to get down to his playing weight of 340 pounds. According to Billick, Anderson has more work to do. "He still needs to get in better physical shape and shed a little weight," Billick said. ... Linebacker Ray Lewis intercepted a pass that deflected off a receiver's helmet and then dashed upfield, running over his position coach, Mike Singletary. … Rookie outside linebacker Terrell Suggs continues to beat tackles to the punch on the pass rush. "He's hard to handle," Billick said. "It would be nice if I could see that in a game." … The Ravens announced that the exterior signage for M&T Bank Stadium will be installed today.
