CHAMPAIGN, Ill. (AP) Andres Feliz scored 23 points and grabbed 11 rebounds and Illinois Fighting Illini beat Nicholls State Colonels 78-70 in overtime on Tuesday in a season opener for both teams.

Ayo Dosunmu scored 21, Giorgi Bezhanishvili added 11 points, and freshman big man Kofi Cockburn had 10 points and 11 rebounds for the Fighting Illini.

Nicholls State was led by Dexter McClanahan's game-high 25 points. Elvis Harvey Jr. added 16 points for the Colonels.

Illinois was up 30-19 at the half and led by 20 points early in the second half before going cold. Nicholls State went on an 8-0 run late in regulation to tie the game at 64-64 with 1:48 left. Meanwhile, the Illini went the final five minutes of regulation without a field goal.

''I thought we were outplayed tonight,'' Illinois coach Brad Underwood said. ''We just weren't mentally tuned in. Don't get me wrong, I'm thrilled we won the game. But we'll do better next time.''

Nicholls State coach Austin Claunch did not meet with the media following the game.

NEVER TOO LATE

Down 66-64 after Harvey's two free throws with less than two minutes left, the usually hot-handed Trent Frazier scored his first points of the game, sinking two free throws to send the game to overtime.

''It was obviously a tough game tonight,'' Frazier said. ''I just have to find a way to help us win.''

Illinois finally warmed up in the extra frame, with Feliz hitting two field goals and two free throws to seal the victory.

''I'm a team guy,'' Feliz said. ''And I'm going to do what the team wants and needs.''

THE BIG MEN

Giorgi Bezhanishvili (6-foot-9) and Cockburn (7-0) provide considerable height and strength under the basket, but Underwood wants more.

''There should be collisions under that rim, like freight trains, with those two in there,'' Underwood said. ''We had some of that tonight, but we need more.''

The pair combined for 21 points and 18 rebounds Tuesday.

''They'll get there,'' Underwood said. ''It's just a matter of time.''

CHARITY STRIPE

Illinois won the game at the free-throw line, sinking 19 of 29 to the Colonels' 8-of-9 effort.

''I couldn't be happier about our free throws,'' Underwood said. ''Given our past there, I thought we did a nice job at the line when it counted.''

HE SAID IT

''Everyone thought we were going to win, so Nicholls State had nothing to lose. So, they went out and made their shots,'' Dosunmu said. ''We just need to keep on winning, no matter what. Rome wasn't built in a night.''

BIG PICTURE

Illinois was expected to coast past Nicholls State, but poor shooting (27 of 61 from the field) and turnovers (Illinois had 23 to Nicholls State's 16) made things a lot closer than they should have been. It could be rust or just opening night jitters, but coach Brad Underwood's squad needs to get it together before starting a two-game road trip.
