Draughn, 25, was brought in to return kicks for Baltimore. On Monday, the team re-signed wideout Tandon Doss to help fill some of the multi-faceted role vacated by Jones, who is expected to miss four to six weeks with a sprained MCL.
The Ravens count on Jones extensively both in the passing game and the return game, so it's not a big surprise that they'd perhaps need more than one player to handle those responsibilities.
Draughn is entering his third season in the league. Last year was the first in which he saw real action, however. He played in all 16 games with the Chiefs, rushing 59 times for 233 yards and two touchdowns while adding 24 receptions for 158 yards. He also returned 23 kickoffs for 537 yards.
Update: The Ravens announced that they have placed rookie wideout Aaron Mellette on season-ending injured reserve with a knee injury.
Baltimore selected Mellette in the seventh round of this year's draft and he made the team against tall odds. He caught nine passes for 140 yards and two touchdowns during the preseason before being inactive for the Ravens' opener.
That leaves the team with just four healthy receivers - Torrey Smith, Marlon Brown, Brandon Stokley and Tandon Doss - because of injuries to Mellette, Jones and Deonte Thompson. Placing Mellette on IR makes room for Draughn on the 53-man roster.
