Christian McCaffrey is on the verge of returning to the San Francisco 49ers as the team has opened his 21-day practice window. After struggling with calf and Achilles injuries, his potential return brings hope to fantasy football managers.

While McCaffrey is expected to reclaim his role as the team's primary running back, his initial workload may be limited as the 49ers manage his recovery. His performance in practice this week will be crucial in determining his availability for the upcoming game against the Tampa Bay Buccaneers.
