Jim Irsay was arrested late Sunday night on preliminary charges of driving while intoxicated and possession of a controlled substance.

Irsay tweeted on Oct. 21, 2013, that he hadn't had a drink in more than 15 years. He admitted in a statement in 2002 that he had an addiction to pain killers.

“There are people around the Colts organization who have been suspicious about some of his behavior,” Adam Schefter said Monday morning onSportsCenter.

Irsay has previously acknowledged his struggles with addiction.

Irsay will be subject to discipline from Roger Goodell.

“He’s a sick, sick man,” one source told Bob Kravitz of the Indianapolis Star. “He desperately needs help.” 

Irsay had lost 70 pounds down to 165.

Hakeem Nicks has signed with the Indianapolis Colts on a one-year, $3.5 million deal. Nicks has a shot to earn another $2 million if he maxes out his incentives.

Nicks has spent his entire career with the New York Giants.

The San Diego Chargers have agreed to a three-year, $10.5 million deal with Donald Brown.

Brown, who had a good season at running back in 2013 with the Colts, will receive $4 million in guaranteed money.

Vontae Davis and the Indianapolis Colts have agreed upon a four-year, $39 million deal.

Davis will receive $20 million in guaranteed money.

Davis was acquired by the Colts before the 2012 season for a second round pick.

The San Francisco 49ers have agreed to a four-year, $26 million deal with Antoine Bethea.

Bethea will replace Donte Whitner at safety.

Bethea turns 30 in July and has started every game over the past six seasons.

Arthur Jones and the Indianapolis Colts have agreed upon a five-year worth more than $30 million.

Jones had 4.0 sacks and 53 total tackles playing defensive end for the Baltimore Ravens in 2013.

The Indianapolis Colts have re-signed Adam Vinatieri on a two-year deal.

Vinatieri converted 87.5 percent of his field goals attempts (35 of 40) last season and made 15 from between 40 and 49 yards and four from at least 50 yards.

D'Qwell Jackson received a four-year deal worth $22 million, including $11 million guaranteed from the Indianapolis Colts, according to a league source.

The Cleveland Browns cut ties with Jackson last week.

Jackson is reunited with former Browns coach Rob Chudzinski, who was hired by Indianapolis to assist coach Chuck Pagano after being fired by Cleveland after just one season at the helm.

Jackson led the Browns with 139 tackles in 2013 and has 418 since 2011, fourth most of any player in that span.

The Baltimore Ravens considered hiring Jim Caldwell as head coach in 2008 before deciding upon John Harbaugh.

Caldwell was promoted to head coach of the Indianapolis Colts in 2009 and is now head coach of the Detroit Lions.

"The year that we hired John Harbaugh, Jim was a candidate for our head coach position so I got a chance to spend some time with him during that time," Newsome said last week at the combine in Indianapolis. "But having him in our building for two years and the way he carried himself and the type of man he is, I think the city of Detroit and their fans are going to be very pleased."
