"He's training like he's coming back," Lynch said via Nick Wagoner of ESPN. "I won't speak for him, but all signs are him coming back and being a part of us."
Mack, a former No. 21 overall pick by the Cleveland Browns in 2009, has started all 196 career game appearances. He has started the entire season 11 times over his career, including his 2021 campaign with the 49ers.
San Francisco lost Pro Bowl guard Laken Tomlinson, who signed with the New York Jets during free agency. Tackle Mike McGlinchey is coming off a torn quad injury.
"He had a significant surgery to repair that quad tendon," Lynch said earlier this month of McGlinchey. "But just as Mike has always done, he attacks everything 100 percent, and his rehab is going really well."
