49ers defensive tackle Kaleb Ramsey retires after two NFL seasons

SANTA CLARA, Calif. -- After two NFL seasons in which he never appeared on the San Francisco 49ers' 53-man roster, defensive tackle Kaleb Ramsey decided to call it quits Thursday, just two days before players are to report for training camp.

Ramsey, who was a seventh-round pick in 2014 out of Boston College, spent time on the Niners' practice squad and served a four-game suspension for violating the NFL's policy on performance-enhancing substances. He spent his first NFL season on the physically unable to perform list because of an Achilles injury.

The 49ers released a statement on Ramsey's retirement Thursday morning, including a quote from Ramsey on his decision.

“I want to thank Jed York, the York family, [general manager] Trent Baalke and all the coaches and staff I have had the pleasure of working with over the last two years," Ramsey said in the statement. "The 49ers took a chance on drafting me and made my NFL dreams come true. Unfortunately, my career has been cut short, as I have made the decision to step away from the game to concentrate on other priorities in my life. During my time in the Bay Area, I have seen how special the 49ers organization and its fans truly are, and that is something I will take with me as I move on.”

Ramsey entered the NFL with a long list of injury issues. He spent six years at Boston College after getting medical-hardship redshirts because of foot, shoulder, leg and calf injuries of varying degrees.

After spending his first two seasons away from the 49ers' roster, Ramsey was expected to compete for a rotational role on the defensive line before announcing his retirement. With Ramsey out of the equation, the Niners now have an open roster spot for tackle Anthony Davis, who earlier this week filed the necessary paperwork to apply for reinstatement to the NFL after a one-year hiatus.

In choosing to retire, Ramsey is the seventh 49ers player to walk away from the game since 2014, joining Davis, linebackers Patrick Willis and Chris Borland, running backs Jarryd Hayne and Marcus Lattimore and defensive end Justin Smith.

"The 49ers organization would like to thank Kaleb for his contributions to our team and our community over the last two years," Baalke said. "We will continue to support Kaleb and wish him well as he moves on from his career in football."

The 49ers are slated to report for training camp Saturday, with the first practice set for Sunday morning.
