Broken Leg: 10 days.

Unfortunately my worst took place about 2 seasons ago and there is no screen shot to prove my claim. But my worst to date was Rick Grimes with a broken leg. He was out for 10 days. I had too many other injuries that season so I let him ride out the full duration. In addition, once he was healed, I let him recover stamina on his own (no Green Packs). That kept him out another 2 days. In his first game back he pulled a hamstring for a 4 day recovery. That's 16 days total for 2 injuries. He missed more than half the season.
