"McCaffrey Out for Week 18 Due to Calf Strain"

San Francisco 49ers running back Christian McCaffrey will miss the Week 18 game against the Rams due to a mild calf strain, but is expected to return for the postseason. The 49ers have secured the NFC's No. 1 seed, allowing them to rest McCaffrey without risking their playoff position. Coach Kyle Shanahan expressed confidence in McCaffrey's recovery for the playoffs. Additionally, cornerback Ambry Thomas is set for hand surgery but should be back for the divisional round, and the team is opening a practice window for receiver Ray-Ray McCloud following a rib injury.
