NFC West Notes: 49ers, Rams, Seahawks

49ers

• The Athletic’s Matt Barrows writes 49ers S Adrian Colbert could be in danger of being cut following his hamstring injury Monday night. 
• Barrows says Colbert has been passed by S Tarvarius Moore and likely will be behind S Jimmie Ward as well when the latter is healthy. 
• 49ers DC Robert Saleh says Moore has “earned the right to be part of the discussion” to start Week 1. (Eric Branch)
• Barrows adds 49ers DE Damontre Moore has been possibly pushed to the wrong side of the bubble following the strong play of DL Kentavius Street.
• According to NBC Sports’ Matt Maiocco, the 49ers won’t make a decision on backup quarterback between C.J. Beathard and Nick Mullens until cut day.
• Maiocco says Beathard might have the edge ultimately given 49ers HC Kyle Shanahan‘s emphasis on big plays and his comments on Beathard: “Every time C.J.’s in there you’ve got a chance for a big play. He loves the big play.”
• Shanahan said he’s hopeful that C Weston Richburg (knee) will be able to come off their Physically Unable to Perform list next week and play in Week 1 of the regular season. (Branch)

Rams

• According to the Athletic’s Vincent Bonsignore, Rams LB Bryce Hager will step into the starting inside linebacker in base defense, while LB Dakota Allen will play more in the nickel defense. 
• Bonsignore says it’s possible the Rams look outside the building for help at the position. He doesn’t anticipate the team moving Clay Matthews back to inside linebacker full-time. 
• Bonsignore projects third-round RB Darrell Henderson to be the chief backup running back and have 9-12 touches per game.
• Rams HC Sean McVay said LB Micah Kiser suffered a “pretty significant injury” and is expected to be miss an extended period of time. (Bonsignore) 

Rams

• Seattle HC Pete Carroll says the Seahawks “don’t have any concern (second-round WR D.K. Metcalf) won’t be back soon” from knee surgery, per John Boyle of the team website.
• Carroll added the surgery revealed “minimal findings” and Metcalf will be week-to-week going forward. 
• Dr. David Chao commented on a video of Metcalf undergoing electrical muscle stimulation that the receiver’s quad looked atrophied and a timeline of Week 1 might be overly optimistic for the rookie to return to the field or be effective.
