"We signed him to the practice squad. That's it," Buccaneers coach Dirk Koetter told ESPN. "All your practice squad guys are developmental guys you're trying to look at."
Huff, 25, was arrested in New Jersey on Nov. 1 and charged with possession of a 9-mm handgun as well as possessing a small amount of pot.
The arrest occurred after Huff was pulled over for speeding on the Walt Whitman Bridge connecting Philadelphia and Camden County, N.J.
Huff was released by the Eagles on Nov. 3.
"Obviously I'm mad that I put myself in that situation, but you live and you learn," Huff told ESPN. "I'm excited to be here. I'm excited to get going and get used to my new teammates and new players around me and get used to the staff."
A former third-round pick (No. 86 overall) in 2014, Huff had 48 catches for 482 yards and four touchdowns in 34 games over three seasons with Philadelphia.
The Buccaneers also placed defensive end Howard Jones (knee) and running back Atone Smith (knee) on injured reserve. Tampa Bay also promoted running back Russell Hansbrough from the practice squad to the active roster.
