The Broncos may have some interest in Trent Richardson down the road.
Denver recently worked out the 25-year-old running back "for future considerations only," an agent source told KUSA-TV's Mike Klis. The Denver Post's Troy Renck added that the team views him as a potential futures contract option.

NFL teams often work out players throughout the season for future consideration (Denver worked out sixteen players two weeks ago). Some of those players will later be considered for futures contracts.
Players that were not on an NFL team's active roster when the previous season ended are eligible to sign futures/reserve contracts. A team can sign players to futures deals as soon as its season ends, reserving those players for the next season (although a camp invite is all that's really guaranteed).
Richardson is a prospect to sign one of those deals with Denver.
Selected third overall in the 2012 NFL draft by the Browns, Richardson's NFL career has been bumpy. He was traded to the Colts for a first round pick in 2013 before eventually being waived by Indianapolis this offseason.
Richardson spent preseason with the Raiders this year, but did not make the final cut.
In four seasons, Richardson has rushed 614 times for 2,032 yards (3.3 yards per carry) and 17 touchdowns. He has also fumbled seven times, losing two of them.
Richardson worked out for the Bills in October.
Update: Denver worked out a total of eleven players on Tuesday, including three running backs. See the full list here.
