Chris Borland, who abruptly retired from football after just one year with the 49ers, says he is going to return most of his signing bonus to the team.
During an interview Sunday morning, Borland told CBS News' Face the Nation he is returning three-fourths of his signing bonus to the 49ers.
Borland received a $617,436 signing bonus when he inked a four-year rookie deal with the Niners coming out of Wisconsin. He would be returning $463,077 to the team, assuming his three-quarters number is accurate.
The Steelers have resigned linebacker James Harrison to a two-year deal, bringing back the 36-year-old who had 51/2 sacks last year.
The five-time Pro Bowler will be entering his 13th NFL season.
This offseason, there were no questions about whether Harrison wanted to return. He came back to the Steelers in 2014 after a brief 18-day retirement.
