Falcons RE Osi Umenyiora didn't start in last week's win over the Redskins and may play in a reserve role the final two weeks of the season. The 4-10 Falcons have been trying to get looks at younger players. Umenyiora started the first 13 games of the season, but second-year DE Jonathan Massaquoi got the start Sunday. Umenyiora leads the team with his 7.5 sacks. But on a two-year deal as a 32-year-old, Umenyiora may be one-and-done in Atlanta.
