Released during the final roster cutdown and then brought back when Pro Bowl kick returner Jacoby Jones got hurt, Doss delivered one of the biggest plays of the Ravens' 30-9 victory over the Houston Texans.
Doss celebrated his 24th birthday with an 82-yard punt return for a touchdown in the second quarter, the fifth-longest punt return in franchise history.
"It's been a long three years for me," said Doss, a 2011 fourth-round draft pick out of Indiana. "[I always have] high expectations for myself because I always had confidence in what I can do on the football field, it's been a rocky first couple of years. Just having that play in front of my home team fans, that was amazing. Hopefully, I'll just keep doing it."
Doss faked inside to his left before bursting outside to his right and eluding Texans punter Shane Lechler. He tight-roped the sideline closely enough that officials conducted an instant-play review to determine whether Doss' feet remained in bounds before affirming it was a touchdown.
"I thought I stepped out, honestly," Doss said. "I just kept running, though. Everybody was saying, 'Go, go, go.' The only thing I remember was Torrey Smith screaming at me. It was a good feeling. He came running down the sideline.
"A couple of their guys overplayed it, which made me force it back to the right. You kind of get a little hazy. You don't really know what's going on. You just react."
Doss' breakthrough return was a welcome development for the Ravens with Jones out four to six weeks with a sprained medial collateral ligament.
"It was well-blocked, we got the gunners blocked, which isn't easy," Ravens coach John Harbaugh said. "Tandon made a couple guys miss, and then showed some real acceleration up the sideline. It's a momentum-changer for the special teams. Obviously, it was a big turning point in the game."
And perhaps for Doss' career, which included just seven receptions during his first two NFL seasons.
While Jones is out, this is Doss' opportunity to prove himself after being out of work for the first week of the regular season after being cut by the Ravens.
"Coming into this camp, the coaches kept telling me this was going to be a great year for me," Doss said. "Just [being released], it was kind of like a shock to myself. I knew something, one way or another, I was going to be on a team.
"I just didn't know where. Thankfully, the Ravens called me after the Denver game and asked me to come back. It's been a blessing. It was a business decision by them. I'm glad I'm back."
Doss tried out for the Green Bay Packers after being cut by the Ravens, but wasn't signed to a contract.
Now, Doss said he appreciates every practice and takes everything more seriously.
"Yes, time to go to work," Doss said. "Being young, I came out my junior year, just being young and not approaching it like it’s actually my job. It’s hard to realize that. I did a poor job the past two years.
"You know, just taking care of my body and just doing things off the field I shouldn’t have been doing, honestly. My mind wasn’t in it all the way, and I’m glad I had that opportunity to see what I needed to do to change it.”
Cody hurts knee
Backup nose tackle Terrence Cody sprained his left knee and didn't return.
Cody went down during the Texans' opening offensive drive and trainers immediately attended to him. He was helped off the field by trainers, but was able to limp into the locker room under his own power.
