Chris Borland plans on giving back part of his signing bonus to the San Francisco 49ers.

"Absolutely not. To play one year, it's not a cash grab as I've been accused of. I'm paying back three-fourths of my signing bonus. I'm only taking the money I've earned," he said.

"This to me is just about health and nothing else. I've never played the game for money or attention. I love football. I've had a blast and I don't regret the last 10 years of my life at all. I'd do it over the exact same way. From here on I'm looking forward."

Borland had a four-year contract that included a signing bonus of $617,436. Three-quarters of that bonus would be $463,077 and Borland paying it back would give the 49ers a bit of a bump in their salary cap space.

Per ESPN Stats & Info, the 49ers had just under $14.82 million in salary cap space.
