TAMPA — The Bucs will likely be limited by injuries at key positions again Sunday when they play the Giants at home, as WR Vincent Jackson and DE Jacquies Smith were sidelined as the team returned to practice Wednesday.Jackson, who missed Sunday's game against the Falcons with a knee injury, was not dressed for practice — his injury was anticipated to sideline him for multiple games — and Smith still had a boot on his left foot, as he did after Sunday's game, which he left with a sprained ankle.TE Austin Seferian-Jenkins continued to practice and could play for the first time in seven weeks against the Giants, and DT Tony McDaniel was back practicing after missing two games with a groin injury. DE Will Gholston, who was limited by a knee injury Sunday, was back practicing, though he had a brace on his left knee.S Major Wright, who has missed two games with a hamstring injury, remained sidelined, and LG Logan Mankins was given a "vet day" of rest, as he was last week.MORE HONORS: Rookie LB Kwon Alexander was named NFC defensive player of the week for his emotional role in the Bucs' overtime win in Atlanta.Alexander, who had an interception, forced and recovered a fumble, and had a team-high 11 tackles, played two days after his 17-year-old brother, Broderick Taylor, was shot and killed in Alabama. Alexander is the first Bucs rookie to earn the NFC defensive weekly honor since Santana Dotson in 1992 — before Alexander, 21, was born.BACK HEALTHY: RT Demar Dotson, who has missed the first seven games recovering from a preseason knee injury, is back healthy and eligible to play against the Giants, but he said he wasn't sure if he would return to his starting role.Dotson went to Wednesday morning's walkthrough practice and was still working with the scout team."Same old, same old," he said."They haven't told me anything," said Dotson, who would be competing with veteran Gosder Cherilus for the right tackle job. "Out there on the scout team, nothing changed. I'm just going as I've been going the last couple of weeks. I definitely feel ready to go."MOVES: With an eye on Smith's injury, the Bucs re-signed DE Lawrence Sidbury, who had been with them in the preseason, to the active roster.The Bucs also added two players to the practice squad: LB Quayshawn Nealy, a Winter Haven native who played at Georgia Tech and was with the Seahawks in the preseason, and DE Ronald Powell, who played at Florida and was a fifth-round draft pick of the Saints last year.Contact Greg Auman at [email protected] and (813) 310-2690.
