San Francisco 49ers star defensive end Nick Bosa is expected to fully participate in practice next week, which could put him in line to start in Week 1. 

Bosa tore the anterior cruciate ligament (ACL) in his left knee in Week 2 of the 2020 season and has been limited to individual work during training camp.

Head coach Kyle Shanahan told reporters on Monday he expects Bosa to join team drills for the first time next week. 

"That's what we're hoping for," Shanahan said. "If we stay on track, I think we'll see him next week."

Assuming there are no setbacks, that should be enough time for Bosa to be ready for the September 12 season opener at the Detroit Lions. 

The 23-year-old was named NFL Defensive Rookie of the Year in 2019 after making nine sacks in his debut NFL season, then added four more sacks in three playoff games. 

Bosa was the second overall pick in the 2019 NFL Draft out of Ohio State University.
