TAMPA — With Bucs starting center Evan Dietrich-Smith held out of practice all week with flu symptoms, the team promoted undrafted rookie Josh Allen from the practice squad Saturday to the 53-man roster and waived cornerback C.J. Wilson.If Dietrich-Smith cannot play today against the Bengals, backup Garrett Gilkey likely will start in his place. Tampa Bay had to promote Allen to have a second offensive lineman who can handle snaps if Dietrich-Smith isn't active. Allen, who is out of Louisiana-Monroe, was with the team from May until the final preseason cuts, then was brought back to the practice squad Sept. 25.It's not necessarily a good week to have uncertainty at center. The Bengals have one of the league's best defensive tackles in Geno Atkins, who had 12½ sacks in 2012 but has been limited to 1½ this season. SON OF EX-SILVER AND BLACK GREAT JOINS RAIDERS: Oakland promoted running back George Atkinson III from its practice squad and placed cornerback Carlos Rogers (knee) on injured reserve. Atkinson is the son of former hard-hitting Oakland defensive back George Atkinson Jr. The father is most noted for his forearm hit to the head of an unsuspecting Lynn Swann in a 1976 regular-season game, even though the ball was not thrown in the direction of the Steelers receiver. The hit gave Swann a concussion. Atkinson also had hit Swann in a similar manner in the previous season's AFC title game, which also gave Swann a concussion. After the second incident, Steelers coach Chuck Noll referred to Atkinson as part of the "criminal element" in football. Atkinson subsequently filed a $2 million defamation lawsuit against Noll and the Steelers, which Atkinson lost. FOLES BACK IN 2-4 WEEKS?
