Colin Kaepernick's girlfriend might be taking a toll on the field. Colin hit a slump and football fans say it's because of Kaepernick's girlfriend. Other papers are reporting that Colin Kaepernick is cheating on his girlfriend Teyana Taylor with a model named Claudia Nelson, but what matters most is what he brings on the field.

In the movie "Rocky," Rocky Balboa's manager tells the struggling heavyweight to lay off girls because "women weaken knees." In "Raging Bull," Jake LaMotta douses himself with ice water the night before a fight. Colin Kaepernick's slump this season might just be that he's a little worn out.

San Francisco 49ers starting quarterback Colin Kaepernick has been dating the 22-year-old singer Teyana Taylor for a few weeks. The 26-year-old Kaepernick and the 22-year-old Taylor have been seeing each other off and on for weeks and recently became more serious.

Media Takeout asked "How serious? Well, word is that part of the reason why he's been PLAYING SO TERRIBLY lately . . . is that she's TAKING ALL HIS STRENGTH . . . if you know what we mean."

Former 49ers starting QB and Hall of Famer Joe Montana thinks it may be the media attention. Montana told Sports World News "I think that's the biggest transition for him. The worst part about it is everyone is talking to him about it. So it's not like he can relax and let it go and not think about it because everyone brings it up to him every day."

Kaepernick led the 49ers to victories over the Washington Redskins, St. Louis Rams and their archrival Seattle Seahawks. MediaTakeOut.com says that might be because Kaepernick is cheating on Taylor with a model named Claudia Nelson. Nelson used to be NBA player Brandon Jennings's girlfriend. Before that she dated hip-hop artist Drake. Claudia Nelson is also famed as Rihanna's "frenemy."

Easy on the knees there, Colin.
