Announcement expected Wednesday

FORT WORTH, Texas -- TCU and coach Gary Patterson have agreed to terms on a long-term contract extension, according to two sources close to the situation.

TCU has called for a news conference at 11 a.m. ET Wednesday morning.

The sources both said part of the agreement includes pay increases for his assistant coaches.

Patterson, in his 12th season at TCU and ninth as head coach, has an 85-27 record in his tenure. That includes TCU's 12-0 record this season, the school's first undefeated campaign since 1938.

The Horned Frogs are No. 4 in the BCS standings and are expected to play in the first BCS bowl in the program's history. Patterson is one of three finalists for the George Munger Award, given by the Maxwell Football Club to the national coach of the year.

Patterson has been mentioned among possible candidates to replace Charlie Weis for the vacant Notre Dame job, but a TCU official said Monday that the coach had not been contacted.

Patterson has had six seasons of at least 10 wins in his nine years at the helm, including five seasons of at least 11 wins since 2003. He's won three conference championships (two Mountain West titles and a Conference USA title) during his tenure and has taken TCU to eight bowl games, including a 17-16 win over previously undefeated Boise State in last season's Poinsettia Bowl.

Patterson has beaten some top Big 12 teams, including No. 5 Oklahoma on the road in 2005 and No. 20 Texas Tech, holding the prolific Red Raiders offense to three points in a victory in 2006. He is second in all-time wins at TCU, 24 behind Dutch Meyer, who won two national championships in the 1930s and coached for 19 seasons at TCU.

Patterson arrived in Fort Worth as defensive coordinator for Dennis Franchione, who became head coach in 1998. It didn't take Patterson long to put together a solid defense. The Horned Frogs had the No. 1 total defense in the country in 2000, Franchione's final season before leaving for Alabama.

TCU held a national search after Franchione left, but opted for Patterson.

After a 6-6 first season, Patterson's defense led the way, finishing No. 1 in the country again in 2002 as TCU went 10-2 and shared a conference title. TCU was the top defense in 2008 as well, giving the Frogs some momentum for this season.

Currently, TCU is No. 2 in total defense in 2009, just behind the top-ranked Florida Gators. The Horned Frogs also are No. 3 in rush defense and No. 4 in passing defense. Four opponents have recorded season-low point totals against TCU this season.
