49ers' Nick Bosa expected to miss 'a few weeks' with calf injury

ESPN’s Adam Schefter reported that 49ers defensive end Nick Bosa is expected to miss “a few weeks” after injuring his calf in Thursday’s practice. The timeline could rule him out of next week’s Denver game; San Francisco is deciding whether to place him on injured reserve.

Schefter’s report said the expected absence also includes Sunday’s game against the Arizona Cardinals.
