Coach Tony Sparano provided an update on the Dolphins players nursing injuries, and the news wasn't good when it came to one of the team's linebackers. That became official in the afternoon when the team waived/injured second-year player Kelvin Smith.
Smith, a second-year player from Syracuse, went down late in the preseason opener against Tampa Bay while covering a punt and Sparano said Monday it looked like Smith had sustained a "pretty serious knee injury."
The three veterans who sat out Saturday's game, meanwhile, have minor injuries and Sparano describe their status as day-to-day.
The three are defensive end Vonnie Holliday (hamstring), kicker Jay Feely (groin) and linebacker Joey Porter, who tweaked his back in practice last week.
Meanwhile, no further word on cornerback Michael Lehan, who remains on PUP because of an ankle injury sustained during an OTA practice.
In another roster move made Monday, the Dolphins signed OLB Maurice Fountain, a former defensive end at Clemson who has played in both the Arena Football League and the Arena2 league.
