TEMPE, Ariz. (AP) - Washington State coach Mike Leach told the Pac-12 to look at whether Arizona State stole signs last season, joining a chorus of teams accusing the Sun Devils.

The Pac-12 says Leach has taken it too far this season -- fining him $10,000 on Thursday and officially reprimanding him ahead of this weekend's football game between the Cougars and Sun Devils in Tempe.

In a statement, Pac-12 commissioner Larry Scott noted conference rules bar members schools from "disparaging" or "discrediting" other schools.

Leach is not the only person to accuse the Sun Devils of stealing signs.

Utah's players said Arizona State stole signs during a game last year and both Oregon and Washington took the extra step of putting up sheets to block the Sun Devils' view from the other sideline.

The Sun Devils maintain they have done nothing wrong. Pac-12 rules do not prohibit sign stealing unless audio and video equipment were used to decipher the signs.

After opening with four straight wins, the Sun Devils (5-2, 2-2) have lost two of three to fall a game behind No. 19 Utah and Colorado in the South Division.

Arizona this weekend is off, with the Wildcats getting their first bye since the 2014 season. Arizona is home against Stanford on Oct. 29.
