Buccaneers coach Greg Schiano said it's a serious injury, but other than his left arm, Black has full function.
Black, 28, made a helmet-to-helmet tackle on San Diego Chargers running back Ryan Matthews in Sundays' 34-24 win for the Bucs. Black fell to the ground after the hit. His neck was stabilized and he was carried off on a stretcher.
Schiano said he hope Black's injury isn't career-threatening, but "it's too early to speculate," according to the Times.
Black is a former third-round draft pick in the 2007 NFL Draft. He's been with the Buccaneers for his entire six-year career, and has been a regular starter for the last four seasons.
Before his injury, Black compiled 25 tackles and two fumble recoveries in nine games. He has 203 tackles and 3 1/2 sacks in his career.
