49ers roster bubble watch: Offensive line
Lock: Aaron Banks, Jake Brendel, Spencer Burford, Jon Feliciano, Colton McKivitz, Jaylon Moore, Trent Williams
Strong bubble: Jason Poe, Matt Pryor, Leroy Watson, Nick Zakelj
Weak bubble: Joey Fisher*, Corey Luciano*
Long shot: Alfredo Gutierrez, Keith Ismael, Ilm Manning*
When Jaylon Moore went down in practice with what looked to be a serious injury, all kinds of doubt was cast upon what San Francisco would do for its swing-tackle role.
Fortunately, Moore suffered a mere bone bruise and should be considered day-to-day, although the options to replace him in the vital backup role to Colton McKivitz and All-Pro Trent Williams are pretty thin. Matt Pryor and Leroy Watson seemed to be the go-to options, so that reveals a bit about how the 49ers feel about them.
Likewise, the 49ers placed Aaron Banks in the concussion protocol, and that gave Jason Poe a bit more field time.
Will one of the undrafted rookies, Ilm Manning, Joey Fisher or Corey Luciano wind up carving out a niche role at the back end of the roster?
It'll be tough, but signs are pointing to the Niners' O-line depth being a bit problematic.
