Broncos sign WR Andre Caldwell

The Denver Broncos will re-sign wide receiver Andre Caldwell to a two-year deal worth up to $3.45 million, a source told ESPN NFL Insider Adam Schefter.

Caldwell, 28, could fill a larger offensive role in 2014 with the Broncos, who may have to replace free-agent wide receiver Eric Decker.

Caldwell saw limited snaps as the Broncos' fourth receiver last season -- he played 21.5 percent of the offense's plays in the regular season.

A six-year veteran, Caldwell finished the Broncos' record-setting offensive season with 16 catches for 200 yards and three touchdowns.
