San Francisco 49ers defensive tackle DeForest Buckner returned to practice on Friday and did not appear on the team's official injury report. He did not practice on Wednesday or Thursday. Buckner's exclusion from Friday's injury report is certainly good news for his availability.

"He looked good," 49ers head coach Kyle Shanahan said Friday regarding Buckner. "We didn't go full speed but I feel confident with him being right for Sunday. I know everyone is hurting a little bit this time of year but I think he'll be good to go. The rest will hopefully help him for Sunday."

Cornerback Greg Mabin is listed as doubtful on the injury report and Shanahan said on Friday that he is unlikely to play against the Jaguars. Safety Adrian Colbert and wide receiver Aldrick Robinson are out of the concussion protocol and will be available, according to Shanahan.

Below are the official injury reports for the 49ers and Jaguars. Also included are Friday's practice participation reports, which were provided by the 49ers Communications team.
