49ers Chris Borland Retires, Fears Brain Injury.
BERMAN: We have some really shocking news in football. A 24-year-old 49ers linebacker Chris Borland is retiring. He announced this overnight. This guy had a great season, says he doesn't want to risk his health anymore. Andy Scholes with the "Bleacher Report". This has pretty big implications, Andy.</s>ANDY SCHOLES, CNN SPORTS CORRESPONDENT: Yes, it sure does, John. You know, this is becoming a new trend in the NFL. Players are retiring at an early age because they fear the long term effects of concussions and other injuries that can occur while playing football. 49ers linebacker Chris Borland, he's the latest to call it a career after just one season in the NFL. Borland had a bright future in the league after a great rookie season, but decided his future wellbeing wasn't worth the risk. The 24-year-old told ESPN, "I feel largely the same, as sharp as I have been. For me, it's wanting to be pro-active. I'm concerned that if you wait until you have symptoms, it's too late." Borland is the fourth player under the age of 31 to retire early from the NFL in the last month. Apparently, Eagles head coach Chip Kelly is trying to break Twitter on a weekly basis. Yesterday, Kelly brought in none other than Tim Tebow for a workout. Tebow last played in the NFL back in 2012 with the Jets. He was in training camp with the Patriots in 2013, but was cut. And since then, he has been working for ESPN as a college analyst. ESPN reports that the Eagles will not sign Tebow at this time. They already have Sam Bradford and Mark Sanchez under contract for next season. But stay tuned. Who knows where this is going to go? All right.

I saw on Facebook, you're going to go with Harvard all the way? Is that true?</s>BERMAN: I was threatening to be that jerk who picked Harvard to win the whole thing, just because he can't think of anything else to do. I'm not going to be that guy despite my inclination.</s>SCHOLES: Kentucky sounds better, I think.</s>BERMAN: I know, yes. I don't know what to do this time.
