Defensive coordinator Lance Guidry will coach in WKU's remaining two games against North Texas and Troy after being arrested early Saturday morning in Baton Rouge for driving while intoxicated, Athletics Director Ross Bjork said Sunday.

Bjork met with reporters on Sunday and said he would meet with Guidry later that night.

He promised a "stern" punishment for Guidry moving forward, suggesting it could be either a pay cut or a limit on out-of-state recruiting.

"Our plan is not to publicize that. That's an internal matter," Bjork said. "It's going to be a stern message to Lance and to our program that we can't tolerate this moving forward."

Guidry, a Welsh, La., native, rented a car from the Baton Rouge airport and went out Friday night to watch a high school game and do recruiting. 

He came back afterward to the team hotel and performed his standard "bed check," in which he and the other coaches make sure the players are in bed by curfew. That typically happens around 10:30 p.m., Bjork said.

From there, coaches are told to "be smart."

Guidry then met with a friend at the hotel and went to a nearby restaurant.

Local police officers were in the bar in which Guidry was drinking and saw him get in his car and drive, Bjork confirmed. Guidry was then pulled over about a block from the establishment.

Officers noticed Guidry swerve his right side tires onto the center white lines twice and his left tires onto the center yellow lines on Constitution Avenue twice, the affidavit says.

An officer put Guidry through a field sobriety test, which he didn't pass.

His blood alcohol content registered at 0.123.

Guidry was arrested at 1:03 a.m. Saturday morning, according to an affidavit of probable cause obtained by the Baton Rouge Advocate.

He was booked into the East Baton Rouge Parish Prison at 2:51 a.m. on one count of second-degree DWI and improper lane usage, according to the affidavit.

Guidry was released from the facility at 4:57 a.m. on $2,500 cash bond, a jail spokesman told the Herald.

Bjork said he was unsure who posted the bond money for Guidry and suggested it could have come from a family member or a friend.

Bjork also confirmed that Guidry was not wearing any WKU attire at the time of his arrest.

News of Guidry's arrest broke Saturday during the Toppers' game against Louisiana State.

WKU Associated Athletic Director Todd Stewart said Saturday that WKU had no comment and that Guidry would not be made available for comment after the game.

That was by design, Bjork said.

"It had to be about the players and the game — taking on the No. 1 team in the country, which we've never done before," Bjork said. "This could not, and we were not going to let it be, a distraction. Even though it was circulating out there, the right thing to do was just to say, 'You know what?We'll deal with this when we get back.' That's what we decided to do."

Players were not told of Guidry's arrest before or during the game, Bjork said, citing once again the desire to keep the focus on the game.

When Head Coach Willie Taggart was asked during the postgame press conference about Guidry's DWI and his decision to let him coach Saturday night, junior tight end Jack Doyle was noticeably perplexed.

Bjork suggested that not telling players about Guidry's arrest didn't send any sort of mixed messages.

"If at one o’clock in the afternoon, we would’ve pulled Lance off the sideline, to me that would have been more detrimental to the team and their psyche than it was sending the message on the discipline," Bjork said. "Lance’s discipline should not affect what the team does and how they respond."

The affidavit states Guidry has been arrested twice before for DWI, in April of 1990 and September of 2003.

The first came when Guidry was in college and the other, in 2003, was too far back for Bjork and those who hired Guidry to notice when they did their standard background check. Federal law only allows a seven year window for background checks, Bjork said.

"If he got that in September of 2003 and we do our background check in early February of 2011 when he was hired, it doesn't catch that," he said. "We're going to work with Lance on the next steps in helping him in any way we can. He's part of our family. He knows he made a big, big time mistake that can serve as a distraction to our program.

"We're going to work with him on making sure this doesn't happen again. Frankly, we can't allow it to happen again."

In the aftermath, Bjork said he looked at "every option" regarding Guidry. That included possible termination, suspension or holding Guidry out of Saturday's game.

"You have to," Bjork said. "You have to look at everything.”

Bjork released a statement Sunday afternoon and said Guidry met with him and Taggart prior to Saturday's game to tell them of his arrest and the details of the night before.

Bjork said Guidry's story matched that of the public police report. That was another reason why Guidry was allowed to coach Saturday.

"Because of Lance’s contriteness and honesty after the arrest and the information we gathered, it was decided that he would coach the game," Bjork said in the statement.

Taggart said in a statement on Sunday that Guidry's actions "were not consistent with (WKU's) value system" and "how we must operate."

Bjork said there's no policy for coaches when it comes to curfew. He said one might be enacted in the wake of Guidry's arrest.

Bjork also said Guidry would likely not be made available for comment regarding the incident.

But Guidry also released a statement on Sunday in which he took full responsibility for his actions Saturday.

"I would like to apologize to my family, our players, coaching staff, administration and fans for the undue attention my poor judgment has caused," he said. "Our football team put forth a tremendous effort against the nation's top ranked team, and I have done a disservice to our entire program by shifting the focus away from where it belongs. I accept full responsibility and the consequences for my actions. 

"I can assure everyone associated with our program that I have learned from this and it will never happen again. I will do everything in my power to gain back the trust and confidence from those I have let down. It is an honor and a privilege to be a Hilltopper, and I will prove that more than ever moving forward."
