DE Jeremiah Attaochu. The 49ers added another contender for their Leo defensive end position in Attaochu, who already is familiar with the scheme having played last year under Gus Bradley with the Los Angeles Chargers.
G Jonathan Cooper. The 49ers signed Cooper, the seventh overall pick in the 2013 draft, to a one-year deal.
LB Brock Coyle. The 49ers and Coyle agreed to terms on a three-year deal Wednesday. He began the season as a special teams stalwart, but ended up starting 10 at middle linebacker after injuries – and NaVorro Bowman's exit – struck the position. Coyle is recovering from shoulder surgery this offseason. “Brock stepped up big for us last season when we experienced some adversity at the linebacker position,” 49ers coach Kyle Shanahan said in a statement. "He’s a selfless guy that does everything the right way. We’ve always known Brock to be a guy we can count on and it was great to see him play the way he did when given the opportunity.”
P Jeff Locke. The 49ers signed the left-footed Locke, a 2013 fifth-round pick of the Minnesota Vikings, on Monday. With Bradley Pinion signed for just one more season, he becomes at least a candidate if the team can't extend Pinion. Perhaps more significant, he gives Pinion – who also handles kickoffs – some relief during the offseason.
RB Jerick McKinnon. The 49ers signed the former Vikings running back to a four-year deal Wednesday. He is expected to be the lead back in a rotation that will include former Georgia Southern teammate Matt Breida and others.
RB Raheem Mostert. He signed his one-year exclusive rights tender, meaning the team's top special teams gunner again will compete for a role on the 53-man roster.
OL Weston Richburg: The 49ers signed Richburg – who played guard but mostly center for the Giants – to a five-year contract Wednesday. He and Daniel Kilgore likely will compete for the starting center role in San Francisco. General manager John Lynch offered no specifics on where Richburg will play. "We see Weston as one of the top young interior offensive linemen in the NFL," he said in a press release. "His athleticism, intelligence and attitude are a perfect fit for our scheme."
CB Richard Sherman. The longtime Seattle Seahawks cornerback signed a three-year deal with the 49ers on Sunday. Sherman is expected to be fully recovered from two Achilles' heel procedures by the start of training camp in late July.
DE Tank Carradine. The former second-round draft pick plans to sign a one-year deal with the Raiders after having visited Oakland and Seattle. Carradine never played as a traditional 4-3 defensive end -- his college position -- in San Francisco and will get a chance to do so with Oakland.
G Brandon Fusco. Fusco signed a three-year deal with the Atlanta Falcons. He started all 16 games at right guard last year for San Francisco.
RB Carlos Hyde. He signed a three-year deal with the Cleveland Browns.
DE Aaron Lynch. He agreed to terms on a one-year deal with the Chicago Bears. Their defensive coordinator, Vic Fangio, was with San Francisco when the 49ers drafted Lynch in the fifth round in 2014.
49ers free agents
S Eric Reid. With Jaquiski Tartt penciled in at strong safety, Reid is unlikely to be back if there's a market elsewhere. What will his market be? It was quiet a week into free agency and Reid said he knew why.
CB Dontae Johnson. Johnson visited the Seahawks on Tuesday, March 20. He played more snaps than any other 49er in 2017 -- 1,224 total -- and therefore led the team in performance-based pay at $91,000.
TE Logan Paulsen. He visited the Lions on Monday, March 19.
