Quinton Patton signed with the Jets on Thursday, the team announced.
The 49ers selected the wide receiver in the fourth round (128th overall) of the 2013 draft.
He caught just three passes in each of his first two seasons in San Francisco.
In 2015, he registered 30 catches for 394 yards and one touchdown.
Last season, he recorded 408 receiving yards on 37 receptions.
In the 49ers Week 14 loss to the Jets, Patton caught four passes for 31 yards.
Patton visited New York last weekend.
Wide receiver Quinton Patton, who spent his first four seasons with the San Francisco 49ers, took a free-agent visit to meet with the New York Jets on Saturday, the club announced.
Patton set career-bests with 37 catches for 408 yards last season. The 49ers have not made an attempt to re-sign him as an unrestricted free agent while signing Pierre Garçon, Marquise Goodwin and Aldrick Robinson in the first week of free agency.
Jets offensive coordinator John Morton was Patton’s wide receivers coach in 2013 and ’14 on Jim Harbaugh’s staff with the 49ers. Patton entered the NFL as a fourth-round draft pick from Louisiana Tech.
INDIANAPOLIS – New coach Kyle Shanahan appears to be appropriately underwhelmed with the pieces he inherits from the 49ers’ last-ranked passing offense.
No team in the NFL threw for fewer yards than the 49ers’ average of a meager 181.9 yards per game last season.
Among the 49ers’ obvious offseason priorities are quarterback and wide receiver. The 49ers have no quarterbacks under contract for the upcoming season. And the receiving corps needs a lot of help, too.
The team’s top two receivers from last year – Jeremy Kerley and Quinton Patton – are scheduled to be unrestricted free agents. Kerley led the 49ers with 64 receptions for 667 yards, while Patton caught a career-high 37 passes for 408 yards.
When asked at the NFL Scouting Combine if any of the 49ers’ group of wide receivers and tight ends stand out from his film evaluation, Shanahan was short on praise of the position groups.
“No one in particular,” Shanahan said. “I feel we’ve got a bunch of good players we feel we can compete with, and we know we need to add some, too. We’re going to add as many as we can to help our roster. We also want to have competition, because the more competition we have in OTAs, the more competition you have in training camp.
“If you cut some people at the end of training camp who you feel can play in the NFL, then that shows your organization is going in the right direction, and that’s really our goal.”
Veteran Torrey Smith is the 49ers' most-accomplished receiver. The six-year veteran signed a five-year, $40 million contract with the 49ers in 2015 after averaging 900 yards and 7.5 touchdowns per season in his first four years with the Baltimore Ravens.
In 12 games last season, Smith had career lows with 20 receptions for 267 yards and three touchdowns.
