SANTA CLARA >> Christian McCaffrey’s first practice with the 49ers in 53 days put a smile on not just his face but his teammates’.

Tampa Bay Buccaneers’ defenders will be the ones frowning if McCaffrey prevails through this week’s practices and makes his season debut Sunday at Raymon James Stadium.

McCaffrey’s speed on a simple handoff caught Brock Purdy by pleasant surprise Monday, a welcome-back initiation for last season’s NFL Offensive Player of the Year.

“I was energized and definitely super, super happy,” left tackle Trent Williams said. “Super happy for him that he turned the corner and he was able to go out and do what he loves again.”

For most 49ers, they returned to practice after a five-day hiatus relishing their Week 9 bye. For McCaffrey, he reappeared for the first time in 53 days.

McCaffrey has recovered well enough from Achilles tendinitis in both legs to take the next step toward his season debut, which could come as soon as Sunday’s game at Tampa Bay.

“Obviously our offense is kind of tailor-made to him and some of his strength, so it’s definitely going to be a tremendous lift for us,” Williams said.

Other comebacks at Monday’s brief, no-pads practice were wide receiver Jauan Jennings (hip) and kicker Jake Moody (ankle). Understandably absent was cornerback Charvarius Ward, whose daughter, Amani Joi, passed away last Monday before her second birthday.

McCaffrey and offensive lineman Jon Feliciano had their Injured Reserve practice windows officially opened, technically providing the 49ers three weeks to activate them or nix their seasons. Still on IR amid an Achilles recovery is linebacker Dre Greenlaw, who ran on the side Monday with a helmet on, as Williams gleefully noted.

McCaffrey, last season’s NFL Offensive Player of the Year, has worked out behind closed doors and rehabilitated his Achilles while the 49ers got off to a 4-4 start, which has them a half-game out of the NFC West lead behind Arizona (5-4).

Without McCaffrey, the 49ers’ run game has produced the league’s fourth-most yards, behind eight-game starter Jordan Mason (685 yards; 5.1 yards per carry) and ascending rookie Isaac Guerendo (227 yards; 6.1 ypc). However, the lack of McCaffrey’s receiving ability and all-around presence have impacted an offense that has produced 19 touchdowns and 21 field goals.

After bypassing the 49ers’ voluntary workouts to train on his own in the offseason, McCaffrey’s calf issues resurfaced a week into training camp, ruling him out for the preseason and a month of practice.

He came back Sept. 3 but was a game-day scratch from the Sept. 9 opening win over the New York Jets. He was limited in two ensuing practices before sitting out the Sept. 13 session and going on injured reserve for his first time in two years with the 49ers. As the 49ers headed to Los Angeles for their Week 3 visit to the Rams, McCaffrey traveled to Germany for advice and presumed treatment on his Achilles, with the 49ers’ blessing.

MOODY’S PROGRESS >> Kicker Jake Moody believes there is a chance he’ll return from a three-game absence and play Sunday. He’s progressed from kicking foam-based footballs to the standard NFL pigskin.
