TAMPA — The Bucs will go into Sunday's game against the Carolina Panthers short at the cornerback position, potentially being without both starters.Carlton Davis is out for Sunday's game with a knee injury after not practicing all week and Brent Grimes is listed as questionable with a knee injury. He went on the team's injury report with a knee injury Thursday and didn't practice Friday.Add in the absence of M.J. Stewart, who is working his way back from a foot injury, and Vernon Hargreaves' season-ending shoulder injury following the season opener, and the cornerback position has been ravaged by injuries."We're down there a little bit," Bucs head coach Dirk Koetter said. "We'll see how it sorts out Sunday. Whoever is going to be out there is going to be competing."The Bucs defense will likely get outside linebacker Lavonte David back from a knee injury following a two-game absence, as well as safety Justin Evans, who also missed the past two games.Offensive tackle Demar Dotson, who left the 49ers game with knee and hamstring injuries, did not practice Thursday or Friday and is listed as doubtful for Sunday's game. Leonard Wester filled in for Dotson on Sunday, playing 46 snaps against the 49ers.Rookie running back Ronald Jones will be cleared for his first game in more than a month against the Panthers.Jones, a second-round pick, has missed the past four games with a hamstring injury."Ronald will be up this week," coach Dirk Koetter said. "As far as his role, we'll see on Sunday.Jones was a healthy inactive for the first three games of the season, buried on the Bucs' running back depth chart. In four games, Jones has run for just 42 yards on 19 carries and has made six catches for 34 yards.Contact Eduardo A. Encina at [email protected] Follow @EddieInTheYard.
