Demaryius Thomas

Peyton Manning reassured Denver Broncos officials, including general manager John Elway, that he is physically and mentally prepared to play at a significant level in 2015, league and team sources told ESPN's Chris Mortensen.

The two sides met Thursday in Denver and while retirement technically remains an option for Manning, it is not one he expressed to Elway and CEO Joe Ellis, sources said.

Manning took it upon himself to get a comprehensive evaluation from a renown performance manager and trainer, Mackie Shilstone, during the past 2½ weeks in New Orleans. Shilstone, who was worked with several elite athletes in the latter stages of their careers, has given the quarterback a strong assessment based on numerous workouts and tests, a source said.

The quad injury that plagued Manning at the end of the 2014 season is fully healed.

Manning first popped up on the injury report with a thigh injury after Week 15 (vs. San Diego). When looking only at his first 13 games, Manning averaged 301 yards, 2.8 TD and 0.8 INT, or 21.4 fantasy points per game. That would have been good enough for the third-highest average if he were able to keep that pace. In the final three weeks, including the game in which he injured the thigh, Manning averaged 272 yards and just 1.0 TD versus 1.3 INT. Even with the reduced production, Manning finished as the #4 quarterback in 2014. If he's fully healthy and ready to go, we'd expect him to be selected in the top 5 in 2015 fantasy drafts, though the Broncos' activity in free agency (namely re-signing Demaryius Thomas and Julius Thomas) will impact his value.
