The San Francisco 49ers officially placed ILB Chris Borland on the reserve-retired list Monday, according to the NFL transactions release.
This move ensures that the 49ers still control his rights in the event he changes his mind about retiring from the NFL.
Shortly after Patrick Willis announced that he was calling it a career, Borland surprised everyone by announcing that he too was walking away from the game.
Borland, 24, has three years remaining on his four-year, $2.897 million contract and would make base salaries of $530,000 (2015), $620,000 (2016), and $710,000 (2017) coming his way over the remainder of his contract.
In 2014, Borland appeared in 14 games and recorded 107 tackles, one sack, two interceptions, a fumble recovery, and five pass defenses. Pro Football Focus has him rated as the N0. 4 inside linebacker out of 60 qualifying players.
