TUSCALOOSA, Ala. (AP) -- Alabama coach Mike DuBose denied rumors that offensive playcaller Charlie Stubbs has resigned effective at the end of the season.

The rumors swirled Tuesday amid questions about the Crimson Tide's offensive pecking order after they were shut out for the first time in three years by Southern Mississippi last Saturday.

"I'm trying not to get mad," DuBose told a roomful of reporters Tuesday night. "I'm going to say this one time --and I'm only going to say this one time -- so listen carefully. There is no validity to the rumors out there, and I'm not going to say anything else about it.

"Let it go. Let us do our job."

Stubbs has declined interview requests the past two weeks.

The Tide (1-2) has struggled badly on offense and has fallen out of the national rankings after entering the season ranked No. 3.

DuBose hired Stubbs in 1998 to open up the Tide's offense with a passing attack honed at UNLV and under Brigham Young's LaVell Edwards. Alabama has returned to more of a run-oriented, I-formation plan the past two weeks.

DuBose also announced Monday that offensive coordinator/line coach Neil Callaway would join Stubbs in the press box on game day.

DuBose and Callaway both said Stubbs would still be calling the plays.

Stubbs has been mentioned as a candidate to replace Edwards when the BYU coach retires after the season.
