Bush has been in the NFL for eight seasons since being selected second overall in the 2006 Draft, and is currently with his third team in that timespan.
"I feel good at this point, obviously I'm saying that because I'm not getting hit right now," Bush told ProFootballTalk.com.
"I still feel like I can go, I don't know how many years left, god willing I can play at least another 5 years. I would love to get at least another five years in."
The 28-year-old had 1,006 rushing yards and 506 receiving yards along with seven touchdowns in the 2013 season.
