Clint Moseley is a redshirt junior who took over as the No. 1 quarterback last year at halftime of the Florida game.
"We had a really good week of practice with all of the quarterbacks," Chizik said.
"Both of them came out, starting on Sunday night, and were really focused," noted Chizik, who said that Jonathan Wallace, the no. 3 quarterback, also had a good week of practice.
The coach pointed out he would like for Wallace, a true freshman, to take a bigger role this week. "We would like for that to happen," he said. "
So far Wallace has seen spot duty as a runner in two games. He carried the football three times for 15 yards vs. LSU and two times for 11 yards last week. He has yet to throw a pass.
Jonathan Wallace signed with the Tigers in February.
"Jonathan is one of those young guys who is very committed and wanting to learn," Chizik said of the former Central High star from Phenix City. "He is just very committed to football. He has done his job every time he as been in there."
Frazier completed 9-14 passes for 118 yards last week as he saw action in the first two quarters. He threw one interception. The Tigers did not score with him at quarterback vs. the Razorbacks.
Making his first game appearance since starting in Auburn's bowl victory over Virginia to close the 2011 season, a game in which he was injured and replaced by Trotter, Moseley replaced Frazier at halftime last Saturday and completed 13-21 passes for 163 yards with two interceptions and a 21-yard touchdown pass to Emory Blake.
Moseley has been battling a sore shoulder that limited his practice time in spring drills. The problem came up again in preseason practices in August, paving the way for Frazier to open the season as the starter.
Moseley, a former Alabama Mr. Football from Leroy High School, had his best game of his collegiate career against Ole Miss last year. He threw four touchdown passes in that Auburn victory.
The Tigers finished their on-the-field preparations for Saturday morning's game with a light workout in shorts that lasted 80 minutes on Thursday evening in which the offense and defense rehearsed their game plans for the SEC West road game vs. Ole Miss.
TV/Radio Coverage: Kickoff for the Ole Miss game is set for 11:21 a.m. on Saturday with TV coverage on the SEC Network. Dave Neal will do the play by play, Andre Ware is the analyst and Cara Capuano is the sideline reporter.
Radio coverage is on The Auburn Network across the Southeast and can also be heard on Sirius Channel 137 and XM Channel 199. Rod Bramblett handles the play by play, Stan White is the analyst in the press box, Quentin Riggins is the sideline reporter and commentator, Andy Burcham does pre-game and post-game updates and Paul Ellen is the studio host.
At Vaught-Hemingway Stadium: Tiger fans making the trip to the Ole Miss campus should have good weather on Saturday. There is no chance of rain in the Saturday forecast with the temperature expected to reach a high of 79 degrees.
SEC Road Trips: Since the league went to divisional play in 1992, Auburn has a .580 winning percentage in SEC road games. Not counting the conference's two newcomers in 2012, Auburn is ranked fifth as a road team in winning percentage since divisional play began. Florida is the only team to have a better than 70 percent record on the road during that period at .747. Vanderbilt has the worst mark at .171.
No Longer Perfect: Cody Parkey suffered his first field goal miss of the season last week from 49 yards out, ending a streak of nine consecutive makes going back to last year. Parkey is now 2-3 on field goals of 40 yards or longer this season.
The longest made field goal in the SEC this year is 52 yards by Marshall Morgan of Georgia. Caleb Sturgis of Florida, who is 3-3, and Taylor Bertolet of Texas A&M, who is 1-1, are the league's two kickers without a miss in the 40 yards and out range.
Dismukes Out: Tunde Fariyike is expected to get his first start at center in place of Reese Dismukes, who is injured. Fariyike started the opener vs. Clemson when Dismukes was out due to a suspension.
More Starters Hurting: True freshman Avery Young, who started the first three games at right tackle, is injured and not expected to play vs. the Rebels. Patrick Miler, another true freshman who has started the past two weeks, is expected to get his third start on Saturday. Two other players who have started this season, junior defensive end Dee Ford and junior cornerback Chris Davis, have also missed practice time this week with injuries, Chizik noted. He has not said what their availability is for Saturday's game. Backup offensive guard Christian Westerman is also out with an injury.
Points Off Turnovers: The Tigers have only intercepted one pass this year and have recovered five fumbles. They have scored just 13 points off turnovers. In the SEC, only Kentucky, which has no points off seven forced turnovers, is behind the Tigers. Alabama, which has forced 15 turnovers, has a league-high 84 points from those takeaways.
New Look On Return Teams: With Quan Bray back from a one-game suspension, the sophomore is expected to resume his duties as one of the two deep men on kickoff returns. However, Onterio McCalebb, who has two returns for touchdowns (versus Alabama in 2011, versus Mississippi State in 2012), will be replaced by tailback Tre Mason, according to special teams coach Jay Boulware.
Last year against Utah State as a true freshman, Mason returned a kick 97 yards for a score. Auburn has five kickoff returns for touchdowns since Boulware took over as special teams coach in 2009. Demond Washington raced 99 yards vs. Georgia in 2009 and 95 vs. Ole Miss in 2010.
