The Denver Broncos brought back wide receiver Andre Caldwell and brought in Emmanuel Sanders to bolster their wide receiver group following Eric Decker's departure.

They also quietly completed a bit of housekeeping that will keep Wes Welker in town. TheMMQB.com's Peter King notes that Denver exercised its 2014 option on Welker, who will make $8 million this season. He's scheduled to be a free agent this offseason.

There were a few questions about Welker's future because of his concussions in his first season in Denver, but coach John Fox indicated back at the NFL Scouting Combine that he wasn't going anywhere. Welker brushed aside questions that he would consider retirement.
