Reserve offensive lineman John Urschel, a natural guard whose first regular-season foray at center two weeks ago in place of starter Jeremy Zuttah was an adventure, was emphatic that his issues with snaps from the shotgun formation wouldn't return if he's called into action Sunday.
When asked if he was confident the issue is behind him, Urschel simply said: "Yes, absolutely."
After the morning walkthrough on Wednesday, Urschel spent extra time on the field with offensive line coach Juan Castillo and long snapper Morgan Cox.
"I've just been working on my snapping technique," Urschel said. "That's what Morgan does for a living, so he had a lot of good insights for me. It's tough to simulate, but it was good for me to get the experience [against San Diego]. … I just hope it's something I can learn from and work to improve from that point on."
Pierce fitting in with Jaguars
Jacksonville coach Gus Bradley said former Ravens running back Bernard Pierce, who was waived after his St. Patrick's Day DUI arrest in March, "has been a great addition to his team.
"I think that he's understanding," Bradley said on a conference call. "He has never played a lot of special teams before, and he's starting to play quite a bit of special teams. So, that's been new for him, and I think that he brings a certain mindset to the group on offense."
Pierce had 353 carries for 1,334 yards and five touchdowns in three seasons with the Ravens, but has six carries for 11 yards with the Jaguars.
Harbaugh said Steve Smith Sr. was in "great spirits" after his surgery Monday to repair a torn Achilles tendon. "He's looking forward to the rehab, and he was pretty fired up about the way it went," Harbaugh said. Jimmy Smith said the practice field was quiet without him. "You can hear a pin drop," he said. … Punter Sam Koch was first at his position in the first round of fan voting for the Pro Bowl, released Wednesday, while kicker Justin Tucker was second at his position. They were the only Ravens in the top two at their positions.
