49ers face offensive line uncertainty in lead-up to Rams opener

The San Francisco 49ers are contending with significant offensive line concerns ahead of their September 10 opener against the Los Angeles Rams in Melbourne, Australia. The team has unresolved competition at left guard and questions surrounding the health of starting right guard Dominick Puni. Puni has recently faced residual concussion symptoms and did not practice, while the left guard spot remains open with Connor Colby, Robert Jones, and Carver Willis vying for the position. Head coach Kyle Shanahan indicated the decision is close, but injuries have complicated evaluations. The Rams' defensive front presents a considerable challenge for an unsettled offensive line.
