Steve Smith injured his shoulder in one on one drills v/s Chris Gamble Monday. X-rays are negative,so there's no structural damage, but it's currently being considered a sprain that would keep him out for a minimum of two weeks - and likely out most of preseason as a precaution.
Preseason impact: Dwayne Jarrett's time has come. Jarrett most likely starts in Smith's place, even though he traditionally backs up Muhsin Muhammad. Jarrett hasn't done much since being a 2nd round pick in 2007- arguably the most disappointing of a draft class that has a Pro Bowler and up to three potential starters already. Muhammad himself may not play, so Jarrett will likely be the most talented receiver out there for Carolina in preseason.
Ryne Robinson looks to play the 3rd receiver role, and would take deep balls and set plays that Smith would run. Robinson, coming off a torn ACL, has plenty to prove as well - he's got competition for the slot role, the 4th receiver roster spot, and for the kick return job. Kenny Moore and Jason Carter are the other alternatives, and likely the players who would play with Robinson on the second team.
And, in what will likely be a recurring theme in the next few years, Mike Goodson is a wild card in the mix - he's been practicing as a slot receiver and may get work at receiver in preseason. However, with Deangelo Williams facing a minor toe injury and Jonathan Stewart facing a minor Achilles issue, both will likely see minimal snaps in the opening preseason game, so Goodson would see a lot of work there.
