At this point, I'm not sure if it makes a huge difference whether or not Colt McCoy or Seneca Wallace is the starting quarterback for this Sunday's game against the Arizona Cardinals. That is not a dig at McCoy; it means that we have pretty much seen what McCoy has to offer given the talent he is surrounded with, and the next three games likely aren't going to make or break his chances at being the team's starter next season.
McCoy did not practice Wednesday or Thursday. He was sent home both days as he continues to recover from the concussion-like symptoms after last week's game against Pittsburgh. Seneca Wallace has been getting all of the reps with the first-team offense, and if we find out that McCoy doesn't practice Friday, Wallace would probably end up getting the spot start against Arizona. "[Seneca's] taken all the reps to this point and in the event that Colt doesn’t play, and the longer he goes here this week without practicing, the more we can assume that that may be the case [that Wallace would start]."
Shurmur also expressed confidence in third-string quarterback Thaddeuis Lewis in the event that he is called upon this Sunday. "I watched him execute in St. Louis. My thoughts go back to, it was a preseason game against the New England Patriots and he went out and executed extremely well. Now, it was a preseason game, but I watched him do some things that make me think that he has a chance."
Safety T.J. Ward took part in portions of practice on Wednesday, but was held back on Thursday after being sore. He hasn't played in a game for awhile, but his status for this week's game will probably be determined by whether he takes part in practice on Friday as well.
Fullback Owen Marecic and tight end Ben Watson have each had multiple concussions this season, and neither one practiced Wednesday or Thursday. It would not surprise me to see Evan Moore start at tight end with Jordan Cameron as the backup this week. That would put Alex Smith in position to start at fullback again.
After missing practice on Wednesday, Joshua Cribbs took part in individual drills Thursday and is expected to play this Sunday. Running back Peyton Hillis appears to have recovered from his hip strain and is ready to roll against Arizona too.
