49ers' initial 53-man roster announced, but more moves ahead before opener

The San Francisco 49ers unveiled their initial 53-man roster on Sunday, though several adjustments lay ahead before the team's opening game on September 10 in Australia against the Rams. Offensive lineman Austen Pleasants (62) was placed on injured reserve, which means he will miss at least the first four games. Brett Toth, the backup center, was also placed on injured reserve without a return designation, and this led to the team's acquisition of interior offensive lineman Jarrett Patterson through trade.

Punter Corliss Waitman and long snapper Jon Weeks were released, but they could be re-signed as veterans by Monday. The 49ers kept seven linebackers in the lineup, exceeding the typical number for that position. Additional moves are expected in the coming days as the team juggles its roster.
