SANTA CLARA (CBS SF/AP) — For San Francisco 49ers star running back Raheem Mostert returning to the playing field amid the COVID-19 outbreak is just part of his job, but it has raised an emotional response from his family.

During a Wednesday remote video call from his Cleveland home with San Francisco Bay Area media, Mostert said fears over the threat of the virus has brought his wife to tears.

Mostert was concerned enough about the pandemic very early. He cancelled a March 4 appearance at an autograph show at the Santa Clara County Convention Center because of those concerns. That was was more than 10 days before Gov. Gavin Newsom issued a state-wide shelter-in-place order, grinding all sports to a halt.

Now more than two months later after more than 90,000 deaths in the United States, including more than 3,000 in California, that worry is still present for he and his wife, Devon, who is expecting the couple’s second child this fall.

“She has actually cried a couple of times just because she wants to make sure not only myself but those 90 guys that are in the locker room are going to all be safe, and their families as well,” Mostert said.

When asked how he felt, the veteran running back said he was willing to do that whatever it takes to return to the field.

“We’ve had talks about it and she understands that no matter what this is my job and I have to do what my job requires me to do,” he continued. “Which is all fair. She’s excited as well, she wants football to be back.”

Mostert said like all players he’s a bit anxious to see just what it takes to start up training camp in July.

“We don’t know what it’s going to take for us to be out back out there on the field, testing every week and playing in a different state or what have you,” he said. “We don’t know yet. That’s something that’s going to be determined once the time comes.”

When that happens, Mostert will look to build on last year’s breakthrough season. After being cut by six teams and carrying the ball only eight times his first three seasons in the NFL, Mostert was a key part of San Francisco’s NFC title winning season in his fifth year in 2019.

He led the 49ers in rushing this season with 772 yards and provided the signature performance of his career on the big stage of the NFC championship game when he ran for 220 yards and four touchdowns in a 37-20 win over Green Bay that sent the Niners to the Super Bowl.

Only Hall of Famer Eric Dickerson has rushed for more yards in a playoff game with 248 for the Rams against Dallas on Jan. 4, 1986.

Despite all that success, Mostert still has never started a game in the NFL as he has been mostly a part-time player who’s only game with at least 20 carries came against the Packers in the playoffs.

He’s preparing for a heavier load if needed this season by bulking up.

“I’m actually gaining some more muscle, which was kind of bizarre just because I haven’t really been able to think about gaining muscle because I’ve already had muscle like that,” he said. “But I’m just trying to incorporate those things in my daily workouts. So I’m able to you know take those hits and be one of those guys that are getting 200 carries. I have to get prepared for that. The only way I know how is to get bulky and stronger.”

Mostert is also looking to become a more versatile player this season on offense. The former college receiver at Purdue has not made a big impact in the passing game as a pro.

He has just 20 catches for 205 yards in his career but hopes to contribute more in that aspect in 2020.

“I don’t want to be just one-dimensional,” he said. “I want to be multi-dimensional and being able to catch the ball out of the backfield is one of the things that I really pride myself on. Even lining up in the slot position. There’s multiple things I’ve been trying to work on. I’m just trying to get back to you know my wide receiver days when I was playing receiver in college. Just getting back used to everything and doing everything.”
