According to two sources, Manning will acknowledge his decision by the end of this week.

These sources also say that Peyton, who will turn 40 on March 24, is leaving the Broncos and retiring from the game he has played competitively for 29 years.

It’s implausible that Manning would opt to sign with another team for one season.

Manning’s final play for the Broncos was a handoff to C.J. Anderson for 5 yards with 1:22 remaining in Super Bowl 50. Manning’s first play with Denver was a handoff to Willis McGahee in the opening moments of a September game in 2012.

In between, Manning threw for 151 touchdowns and 19,062 yards.
