The undrafted rookie caught 72 passes for 1,059 yards in four seasons at Washington. He was waived by the Cardinals on Wednesday. To make room on the roster the Jaguars cut long snapper Trevor Gillette.
Smith should get plenty of work immediately because Jaguars receivers have been besieged by injuries. Seven sat out Thursday's organized team activities, including Cecil Shorts (calf) and second-round draft picks Allen Robinson (hamstring) and Marqise Lee (ankle).
Kerry Taylor, former practice squad player Chad Bumphis, undrafted rookies Damian Copeland and Allen Hurns took all the reps on Tuesday and Thursday. Taylor is the only healthy receiver that has caught a pass in a game. He has 22 catches for 229 yards.
That lack of depth has been somewhat of a hindrance during OTAs.
"It just stalls things because we're not going to run a play and have [them] miss alignments so we just get them aligned and now we run the play," coach Gus Bradley said. "It just slowed down the tempo a little bit but that's OK at this point."
It also is a bit taxing physically on the healthy receivers because they aren't able to take plays off, although the Jaguars did more work with multiple tight ends on Thursday.
