Long-snapper Kyle Nelson, who will serve the final six games of a 10-game suspension, agreed to a four-year contract with the club, a league source told NBC Sports Bay Area.

The deal, first reported by Field Yates of ESPN, locks up Nelson through the 2022 season. Nelson is a seven-year NFL veteran who has handled the 49ers' snapping chores on field goals, extra points and punts since 2014.

Nelson will be eligible to participate in all offseason and preseason practices. His suspension resumes at the start of the 2019 regular season.  The 49ers signed Colin Holba to handle the long-snapping chores in place of Nelson for the final four games of last season.

Hearing there’s a mechanism in long-snapper Kyle Nelson’s contract that enables the #49ers after six games to remain with Colin Holba without any financial impact if things are going well with their specialists and they don’t want to break up that chemistry.

After his suspension last season, Nelson released the following statement through the team:

“I have been taking the same supplements for my entire time with the 49ers, while undergoing often simultaneous testing by the NFL with no issues. I do not deviate from my nutrition routine, and I would never knowingly take a banned substance. I am currently having the supplements tested, and I hope to uncover the cause of the positive test.

"When the product is identified, I fully intend to seek legal action against the manufacturer to protect against this happening to other players in the future.”

Nelson's previous NFL suspension came on Oct. 21, 2011, his rookie year, NBC Sports Bay Area's Jennifer Lee Chan reported.

Kicker Robbie Gould was designated as the 49ers' franchise player. He has yet to sign his one-year, $4.9 million deal. Punter Bradley Pinion is an unrestricted free agent.

Eight days before the NFL trade deadline, 49ers coach Kyle Shanahan said Monday that he does not feel as much urgency to add a veteran receiver in the middle of the season than in his previous two. 

“I think less (urgency) than we’ve had in the last couple of years because I do see that there are guys in our building that I do think the answers are here,” Shanahan told reporters Monday in Santa Clara, amid reports that the 49ers are in the market to add a wide receiver.

The 49ers played Sunday without rookie receiver Deebo Samuel, who injured his groin a week earlier against the Los Angeles Rams. Marquise Goodwin played just seven snaps before leaving with an injury Sunday. He was evaluated for a concussion but was cleared. Goodwin is not in the NFL’s concussion protocol, Shanahan said.

San Francisco also hopes to get Trent Taylor and rookie Jalen Hurd back later in the season. Both players are on injured reserve. They are eligible to return after sitting out eight games from the time they went on IR.

“It was tough not having Deebo last week and Marquise being a little bit banged up, we’ll get both of those two back,” Shanahan said. “The guys we have I still think can continue to get better. We’re still holding out hopes, too, for Jalen and Trent Taylor that they can heal up and hopefully return later this year.

“We’re always looking to improve, but I do like the guys we have here.”

Tight end George Kittle is the 49ers' top pass-catcher with 34 receptions for 376 yards and one touchdown. Samuel leads the wideouts in receptions with 15 catches for 168 yards, while Goodwin has 11 catches for 181 yards. Samuel and Goodwin have one TD apiece. Kendrick Bourne had his best game of the season on Sunday with three catches for 69 yards in the 49ers' 9-0 victory over Washington.

Dante Pettis, a second-round pick in 2018, has not produced up to expectations. He has nine catches for 83 yards and one touchdown.

The NFL is a business, and often times that leads to hurt feelings.

Teams draft players, run them into the ground on the cheap and then decided to either trade them, cut them or not re-sign them when the time comes. Being used breeds animosity, and a lack of loyalty can burn bridges built through years of trust. 

But when it comes to Frank Gore and the 49ers, no such animosity exists.

The 49ers drafted Gore out of Miami with a third-round pick of the 2005 NFL Draft. Gore played 10 seasons in the Bay Area, rushing for 11,073 yards and 63 touchdowns. After the 2014 season, Gore signed a three-year contract with the Colts after the 49ers elected not to offer him a long-term deal.

Gore has gone from the Colts to the Dolphins and now finds himself with the Bills, but he still keeps in touch with the organization that gave him his first shot. 

“I still talk to Jed (York), talk to Paraag (Marathe), I still talk to Scot McCloughan," Gore told KNBR's Al Sacco. "I played 10 years there. I was blessed to play 10, and I know the business of it but I respect Jed. He let his guys make the decision on whether to bring me back and I respect it. Like I said, his mom calls me, his dad texts me here and there. It’s like a family over there.”

The veteran running back remains thankful the 49ers took a chance on him coming out of colllege.

“It’s everything. It was the first given opportunity to be able to play this game at the highest level," Gore told KNBR. "Even though I was coming off two ACLs they still took a chance and they got beat up by taking me with the first pick in the third round.”

Gore recently eclipsed the 15,000-yard mark for his career. He has said he wants to retire as a member of the 49ers when the time comes.

But for now, Gore plans to keep on racking up the yards for the Bills, or whoever else wants him toting the rock.
