Auburn coach Jeff Lebo said his team gave good effort after a physical one-point loss to Oklahoma State on Friday. "We weren't going to back down," Lebo said. "We were going to be physical, we were going to be aggressive and that is what we were.
"We didn't get things to go our way and had some adversity we had to fight through there, but we battled hard," the coach added. "We just weren't good enough. We made it ugly enough though, which is what I thought we needed to do to have a good chance to win."
Auburn returns to action with a Tuesday home game vs. Nicholls State at Beard-Eaves Memorial Coliseum. Tipoff time is set for 7 p.m. Sophomore forward Josh Dollard is scheduled to make his debut after opening season on suspension for violation of team rules.
