Jordan Mason - Likely has AC sprain Mason (shoulder) is believed to have a sprained AC joint but will undergo further testing Friday, Adam Schefter of ESPN reports. Impact Mason left Thursday's win over Seattle in the second quarter, returned for one play after halftime, and then missed the rest of the game. Isaac Guerendo filled in as San Francisco's lead back and iced the game with a 76-yard run in the closing minutes, with Patrick Taylor also taking on some work (five carries, one catch) in Mason's absence. Meanwhile, the 49ers hope to get Christian McCaffrey (Achilles) back at some point within the next few games, although it's not clear if he has any chance to be ready for a Week 7 matchup with the Chiefs on Oct. 20.
