08:02 AM ET 11.14 | After suffering a concussion on Sunday, San Francisco quarterback Alex Smith has reason to want to get back on the field. And while it's unclear whether he'll be cleared by an independent neurologist to return to action on Monday night against the Bears, a league source tells PFT that Smith is seeking a second opinion. It's unclear what impact, if any, a second opinion would have on the assessment of an independent neurologist. Given the somewhat subjective nature of the ultimate assessment of a guy's symptoms, however, a second opinion that points toward a mild concussion or no concussion at all could influence the independent neurologist's assessments. ... If Smith doesn't play and if Colin Kaepernick plays well on a national stage, Alex Smith could be the sports world's next Wally Pipp.
