Cundiff, calling himself a competitor, said he was told Wednesday night that he wouldn't play. Rookie kicker Justin Tucker handled all of the kicking duties, and he made field goals from 33 and 53 yards away.
"It was a shock to me," Cundiff said. "I felt I had a really good week of practice."
Cundiff still participated in pre-game warmups, saying he wanted to get a kicking session in.
"I don't think anybody would be OK with not playing," Cundiff said. "I know there are some certain situations in the preseason where there are guys who are beat up, whatever the case may be. Any time you feel like you're not getting reps -- you want to be the one out there kicking."
Cundiff has made 77 percent of his field goal attempts during his career. Since he entered the NFL in 2002, Cundiff is 83 percent inside of 50 yards. In the past two years, Cundiff is 90 percent inside of 50 yards, having made 53 of his 59 attempts. Cundiff missed two of those in 2010 and four in 2011. However, he missed a crucial 32-yarder that would've sent last season's AFC Championship Game against New England to overtime.
Cundiff has never been much of a long-range kicker, hitting just five of his 17 attempts from 50 yards or longer. But he believes his track record over the last two years should be enough to keep him in Baltimore.
"If they feel as if that's not good enough, then I'll take my services elsewhere," Cundiff said.
He added: "I feel it's a really solid track record. I'm not here to deal in hypotheticals. I'm ready to play football and that's what I get paid to do."
Harbaugh said the decision was made so the coaching staff could see what Tucker could do in a pressure situation, since he's not a "proven" kicker. Harbaugh downplayed the issue, stating the organization knows Cundiff would've made the same kicks Tucker did.
This competition has become closer than expected since Tucker was signed this offseason. Tucker's performance throughout training camp has given Harbaugh and the coaching staff a lot to think about.
"We have to make some decisions here again next week," Harbaugh said. "So we'll just have to see how that goes."
The ankle is fine: Receiver Torrey Smith looked as good as ever Thursday night, hauling in eight catches for 103 yards. He's coming off a minor ankle sprain, but it didn't appear to slow him down.
At one point, he was seen limping on the sideline. But receivers coach Jim Hostler gave Smith motivation to keep playing.
"(Hostler) said, 'You're full of drama, limping'" Smith said. "I just needed to walk it off. I was fine."
Injury report: Safety Emanuel Cook broke his right leg on a special teams play in the second half and will be out for the season. Safety Sean Considine suffered his second concussion in as many weeks, with this one being a major concern. Cornerback Corey Graham sustained a stinger, according to Harbaugh.
RG Marshal Yanda (leg), OLB Sergio Kindle (shoulder stinger), WR David Reed (ACL), LB Josh Bynes (vertebrae), LB Darryl Blackstock (groin), OLB Terrell Suggs (Achilles), OL Jah Reid (calf), TE Ed Dickson (shoulder), TE Dennis Pitta (hand) and DT Ryan McBean (broken ankle) did not play against Jacksonville.
New record: The 48 points Baltimore posted against Jacksonville set a new preseason scoring record. This bested the 38 points scored against the New York Giants during the 2001 preseason.
