Colin Kaepernick keeps us hanging

SANTA CLARA, Calif. -- Colin Kaepernick has been on the injury report at different points of the season with a foot injury. He has shown no signs of discomfort and it hasn’t cost him any practice time. Coach Jim Harbaugh said it hasn’t altered the team’s plans in any way.

Yet, no one would say what the issue is exactly. The quarterback was asked about it Wednesday and he gave this answer: “hang nail.”

Going along with it, a reporter asked what toe? “Pinky,” Kaepernick shot back.

What foot? After a moment, Kaepernick, with a half smile said “both.”

There you go. All solved.

Meanwhile, Kaepernick is entering a three-game stretch against the Tennessee Titans, Jacksonville Jaguars and Carolina Panthers. They are three of the five teams to draft a quarterback in 2011 before the 49ers took Kaepernick in the second round with the No. 36 pick. Kaepernick took a pre-draft visit to Tennessee. He said he thought it went well. The Titans took Jake Locker in the first round instead.

“I definitely haven’t forgotten it,” Kaepernick said matter of factly.
