Peyton Manning’s competitive fire still burns.

Despite lingering injuries (foot, ribs, back) and a noticeable decline in performance, the 18-year NFL vet will not retire at season’s end, according to Mike Florio of Pro Football Talk.

Florio reports that Manning is “absolutely determined” to recover from a variety of injuries and return to form for 2016, according to sources close to the former Tennessee quarterback.

Manning has fought through a challenging year on the field, posting career-lows in completion percentage (59.9), touchdown passes (9) and QB rating (67.6). Brock Osweiler appears to be Denver’s signal caller of the future and sources say Manning would be willing to play elsewhere next season if it comes to that.
