McCaffrey (back) is active for Sunday's game against the Titans.

After an illness impacted his practice participation Wednesday and Thursday, McCaffrey worked fully Friday and initially approached Sunday's contest minus a designation. However, on Saturday the running back was added the 49ers' Week 15 injury report due to a back issue. With his availability versus Tennessee confirmed, McCaffrey is back on track to pace his team's backfield in the absence of any in-game setbacks. Next up for San Franciso's backfield touches if McCaffrey is hampered at all would be Brian Robinson and Isaac Guerendo.

Although he was added to the 49ers' injury report Saturday, McCaffrey (back) is expected to play against the Titans on Sunday, Adam Schefter of ESPN reports.

McCaffrey popped up on Saturday's injury report due to a back issue, but at this time, the injury isn't considered severe enough for him to miss Sunday's contest. If McCaffrey suffers a setback or operates on a snap count, then Brian Robinson, Isaac Guerendo and Jordan James would be in line for more work out of the 49ers' backfield. McCaffrey's official status may not be announced until the 49ers submit their list of inactive players approximately 90 minutes before the 4:25 p.m. ET kickoff.

McCaffrey has been added to the 49ers' injury report due to a back injury, and he is listed as questionable for Sunday's game against the Titans, Matt Barrows of The Athletic reports.

McCaffrey was able to shake off an illness during Week 15 prep, but the veteran running back appears to be working through a new back issue. The injury puts McCaffrey in jeopardy of missing Sunday's game, and his official status may not be known until the 49ers announce their list of inactive players approximately 90 minutes before the 4:25 p.m. ET kickoff. If McCaffrey is unable to play, then Brian Robinson would likely take over as the 49ers' lead back while Isaac Guerendo and Jordan James provide backfield depth.

Evans (collarbone) brought in six of 12 targets for 132 yards in the Buccaneers' 29-28 loss to the Falcons on Thursday night.

Taking the field for the first time since Week 7, Evans looked as good as head coach Todd Bowles had reported the star receiver had during this week's practices. Evans made his first catch for a gain of 12 yards on the Buccaneers' second drive, and he went on to add noteworthy gains of 12 and 33 yards later in the first half. On Tampa Bay's first possession after halftime, the perennial Pro Bowler would go on to add a 45-yard grab, which accounted for half of the yards on a drive that culminated in a Devin Culp six-yard touchdown catch. Evans' receptions, receiving yards and targets were all season highs, and he'll aim to carry over the momentum into a Week 16 divisional road clash against the Panthers on Sunday, Dec. 21.

Evans (collarbone) is listed as active Thursday against the Falcons.

Evans thus is in line for his first appearance since Week 7, when he initially suffered a broken collarbone. Since he returned to practice last Wednesday, he was listed as limited on all six of the Buccaneers' injury reports, and coach Todd Bowles revealed to Rick Stroud of the Tampa Bay Times this Wednesday that Evans has yet to take contact. On Thursday afternoon, Jeremy Fowler of ESPN.com reported that Evans was expected to play in Week 15, but the veteran wide receiver also will be operating under a snap count. As a result, Evans seemingly will be working behind at least Emeka Egbuka and Chris Godwin in the pecking order at the position, while Jalen McMillan (neck), Tez Johnson, Sterling Shepard and Kameron Johnson also will be on hand for snaps and targets.

Evans (collarbone) is officially listed as questionable for Thursday's game against the Falcons, though he's in line to play and is expected to be on a "pitch count" with his snaps, Jeremy Fowler of ESPN.com reports.

Evans' availability won't be confirmed until Tampa Bay releases its inactive list 90 minutes prior to the game's 8:15 p.m. ET kickoff, but he looks poised to play for the first time since Week 7 after the Buccaneers activated him from injured reserve Wednesday. Though the 32-year-old wideout didn't take full contact at any point since having his 21-day practice window opened last Wednesday, the Buccaneers feel comfortable enough with how he's recovered from a broken clavicle to clear him for game action. As Fowler notes, Evans probably won't play his usual complement of snaps, but Tampa Bay plans to have him on the field for its most important downs. If Evans escapes Thursday's contest without incident, he should be ready to handle a fuller workload Week 16 at Carolina.

Tucker rushed four times for seven yards and a touchdown in the Buccaneers' 29-28 loss to the Falcons on Thursday night. He also returned two kickoffs for 42 yards.

Tucker rushed seven times for 29 yards and a touchdown in the Buccaneers' 24-20 loss to the Saints on Sunday.

Tucker rushed twice for no gain and wasn't targeted in the Buccaneers' 20-17 win over the Cardinals on Sunday.

Pierce (rib) was a full participant at Wednesday's practice.

Pierce left the final drive of Sunday's loss at Jacksonville with an undisclosed injury but was not in the concussion protocol despite a broadcast report saying he was being evaluated for a concussion, the Indianapolis Star reports. "You can ask the trainers," Pierce said. "Not going to talk about injuries."

Pierce recorded five receptions (on eight targets) for 80 yards in Sunday's 36-19 loss to the Jaguars.

Otton (knee) is listed as inactive Thursday versus the Falcons.

Buccaneers head coach Todd Bowles said Wednesday that Otton (knee) is considered doubtful for Thursday's game against the Falcons, Brianna Dix of the Buccaneers' official site reports.

Otton (knee) did not participate at the Buccaneers' walkthrough practice Tuesday.
