The Kansas City Chiefs are expected to extend Patrick Mahomes' contract after next season, according to league sources.

It would be the first time the MVP candidate is eligible for an extension and he could receive the NFL's first $200 million contract.

However, some issues will have to be addressed -- some surrounding the collective bargaining agreement that would have only two seasons remaining, and some involving the two years that Mahomes would have left on his current contract, including the fifth-year option that Kansas City undoubtedly would exercise.
