SANTA CLARA, Calif. - Running back Marcus Lattimore has been a fixture on the 49ers' sideline while rehabbing his knee that required reconstructive surgery. But he was not with his teammates during Sunday's 13-10 loss to the St. Louis Rams.
"Did not see Marcus," head coach Jim Harbaugh said postgame. "I'm sure we'll have an announcement about that."
According to a report by ESPN citing a league source, Lattimore is retiring due to knee issues. In his final collegiate game at South Carolina in 2012, he tore every ligament in his right knee and dislocated his knee cap.
Lattimore's teammates also said they had not seen him since last week, when he practiced Wednesday and Thursday for the first time in 2014. He sat out Friday's session and "he hung back in the training room," Harbaugh said afterwards.
The 49ers took a chance on Lattimore by drafting him in the fourth round in 2013 believing he was one of the most talented running backs available when healthy. The team has made a habit in recent seasons of drafting players with injuries and giving them a "red shirt" season to begin their NFL careers.
Lattimore's agent Michael Perrett took to Twitter to refute the report, writing "No decision has been made on @MarcusLattimore 's future."
Last week, an emotional Lattimore spoke about his road back from the injury and what he expected during his first practices of the year.
UPDATE: 12:20 P.M.
In his meeting with the media Monday afternoon, Harbaugh said Lattimore was still weighing his options, noting an official announcement regarding the running back's future will be made within the next two days.
"He’s going to talk to his family. We’re in the process of that right now," said Harbaugh.
"That’s the information we have. When we have more information... exact information, (we will) release that."
Harbaugh would not elaborate about past conversations he had with Lattimore during his comeback that has lasted roughly two years since sustaining the injury in his final collegiate game.
"Rather than speculate and talk now about what the conversations have been or what the options are... I’m sure within the next day or two we’ll have an official announcement," Harbaugh said.
