49ers look to build on strong start after Buckner trade

San Francisco’s veterans have urged the team to strengthen its roster for the season’s second half, and management has responded by bringing back defensive tackle DeForest Buckner. Coach Kyle Shanahan said the current team is stronger than the one at the same point last season, while noting that another acquisition would be welcome but is not something the team is relying on.

The 49ers are 6-1 and had a bye last weekend. Bosa is set to return Sunday after missing five games with a calf injury. He said he was glad Buckner was back and suggested the team already had plenty of depth at defensive end.

San Francisco plays the Raiders at Levi’s Stadium on Sunday and continues to consider possible additions before the trade deadline. The team has been seeking wide receiver depth after injuries at the position. A potential deal to bring Jauan Jennings back from Minnesota fell apart after Jennings indicated he preferred to remain there, Shanahan said.

The situation with Brandon Aiyuk appears headed toward an end. Shanahan said he has no expectation about whether Aiyuk will report to the team facility. If Aiyuk does report, the team may release him after he is removed from the reserve/left-squad list. Shanahan has previously said Aiyuk would not return as a 49ers receiver.
