Manheim, Pa. -- Even with a full slate of college wrestling action last week, there were minimal team changes in the most recent USA Today/NWCA Division I Wrestling Coaches Poll released on Tuesday.

RANKING: USA Today/ NWCA Coaches poll

Top-ranked Oklahoma State, second-ranked Penn State and fourth-ranked Ohio State are the last three Division I unbeatens. Oklahoma State improved to 8-0 with a pair of Big 12 wins, beating West Virginia 38-3 and No. 19 South Dakota State 31-9.

Penn State improved to 8-0 and moved into first place in the Big Ten regular season standings with a 26-11 win over No. 3 Iowa in front of over 14,000 fans at Carver-Hawkeye Arena. The loss was the second in a row for the Hawkeyes, who fell to top-ranked Oklahoma State a week prior.

Despite back-to-back losses, Iowa (7-2) remained third, followed by Ohio State (8-0). The Buckeyes had a 30-12 "home" win over Maryland. The dual was held at Our Lady of Good Counsel High School in Olney, Maryland, and was deemed a home match for Ohio State as Good Counsel is where Buckeye heavyweight Kyle Snyder attended high school for three years prior to moving to the Olympic Training Center in Colorado.

Iowa and Ohio State will meet on Friday in Iowa City. It will be the third straight top-five opponent for the host Hawkeyes.

Virginia Tech (13-1) is steady at No. 5. The Hokies lead Division I in dual meet wins and smashed then-No. 23 Pittsburgh 38-9 and then topped rival Virginia 29-14 in the Commonwealth Cup. The Hokies have won nine in a row.

No. 6 Nebraska (10-1) rallied past No. 13 Minnesota on Friday in Minneapolis. The Huskers lost four of the first five weights, but swept the final five to come away with a 21-11 victory. No. 7 Missouri (9-2) moved up one spot after beating then-No. 16 Central Michigan 24-8.

North Carolina State (8-1) moved up to No. 8 at the Brawl at the Hall in Chapel Hill over ACC rival North Carolina 19-11. The event was held at the Memorial Hall, a theatre on campus. It's one of a number of theatre venues used in recent years as Missouri and Virginia Tech have also used similar backdrops to host home duals.

A battle of EIWA rivals caused a shift in the bottom half of the top ten. Cornell's 21-20 victory over host Lehigh on Saturday moved the Big Red to 7-2 and up to No. 10, while the Mountain Hawks (8-2) slid three spots to No. 10.

Other notable action saw then-No. 21 Stanford upend then-No. 20 Arizona State 21-14 in Pac-12 action. The Cardinal (7-2) moved back into the top 20, while Arizona State slid two spots to No. 22.

Edinboro (6-4) enters the Top 25 for the first time this season after a weekend victory over then-No. 25 Rider in EWL action. It's the first time the Fighting Scots have been ranked this season.
