The Buccaneers activated Pinion (undisclosed) from the reserve/COVID-19 list Friday.
Pinion's stint on the COVID list lasted just four days. He and placekicker Ryan Succop (undisclosed) will both be available for Sunday's game against the Falcons.
Pinion was placed on the reserve/COVID-19 list Tuesday, Carmen Vitali of the Buccaneers' official site reports.
Pinion either tested positive for the virus or came into close contact with an infected person. He's in danger of missing this Sunday's game against the Falcons. The Bucs also placed kicker Ryan Succop and long snapper Zach Triner on the reserve list.
Pinion intends to sign a four-year contract with the Buccaneers, Rick Stroud of the Tampa Bay Times reports.
Pinion served as the 49ers' starting punter each of the last four years, and boasts a career average of 43.7 yards per punt. With Bryan Anger having been released by Tampa Bay, Pinion has a clear path to the starting job in 2019.
