What happened: Nick Bosa said ramping up football work too quickly aggravated his patellar tendon during his recovery from a torn ACL. John Lynch said the complication was unexpected, but San Francisco adjusted Bosa’s workload before taking him to Australia.
Why it matters: San Francisco opens against Los Angeles on Sept. 10 at Melbourne Cricket Ground with Sam Okuayinonu already on injured reserve. Bosa played only three games last season, leaving his availability central to the 49ers’ pass rush.
By the numbers: Bosa recorded 17 tackles and two sacks across three games last season. His Sept. 2 return came 30 days after his previous team practice on Aug. 3.
What to watch: Bosa’s participation in Melbourne practices will offer the next indication of his workload against the Rams.
