Forty-Niners quarterback Colin Kaepernick has never been the talkative type when it comes to speaking with the media, but that wasn't the case on Monday.

During a prolonged interview, not only was Kaepernick talkative, but he also revealed that he's been dealing with several injuries that were previously unknown to anyone outside the 49ers organization.

For one, Kaepernick has been playing his entire NFL career with a metal rod in his left leg. The 49ers quarterback had the rod put in before his rookie year in 2011. Kaepernick's rehab went unnoticed because the NFL was in the middle of a lockout.

"It's just something I've learned to deal with," Kaepernick said of the rod, via the San Jose Mercury News. However, Kaepernick did add that the rod has been bothering him, "Here and there."

Kaepernick is headed for Colorado on Tuesday, where he's expected to have his left leg examined. Besides the leg, Kaepernick will also have his right thumb looked at. The 49ers quarterback revealed that he has a torn ligament in his thumb that might need to be surgically repaired.

"It's been recommended surgery and get confirmation on whether I'll need surgery or not," Kaepernick said. "We'll get it fixed as soon as possible. They haven't given me specific dates as far as how long it will be."

Kaepernick has been dealing with a plethora of injuries over the past few months. The 49ers quarterback was placed on injured reserve in mid-November after the team discovered he had a torn labrum in his left shoulder. Kaepernick underwent surgery on the shoulder a few days after being placed on IR.

As for his thumb injury, although it was just discovered last during an MRI, Kaepernick said he actually suffered it during a Week 7 game against the Seahawks. Kaepernick only played one more game after that before being benched in Week 9 for Blaine Gabbert.

Speaking of Gabbert, Kaepernick was asked if wanted to return in 2016 and play for a team that benched him in 2015.

"I'm under contract. I'm a 49er," Kaepernick said. "I'm doing everything I can to make sure I’m prepared for next season."

The big date to watch out for in regards to Kaepernick is April 1, because that's when his $11.9 million salary for 2016 becomes fully guaranteed. If the 49ers dump him before that, they're off the hook for his salary and would only take a $7.4 million cap hit. 

Kaepernick says he's not really paying attention to that though. 

"For me, that's not a date I'm concerned with," Kaepernick said. "I feel like I'm going to be playing football regardless of April 1, April 2. I'm doing everything I can to be healthy as soon as I can. I'm preparing to be healthy and win the Super Bowl. That's all my focus is."

Kaepernick's future in San Francisco will have everything to do with whomever the next coach is. If the next coach likes Kaepernick, then the team will likely hang on to him. If the next coach isn't a fan of Kaepernick, then there's a good chance he'll be released or traded.
