Ochefu was limited to 13 minutes in Villanova's quarterfinal victory Thursday over Georgetown, going 0-for-2 from the field and failing to grab a rebound.
"He couldn't practice yesterday, so we didn't know," coach Jay Wright said after the game. "We really didn't know. We had a choice to try to let him go yesterday in practice, see what we got -- or rest him and see what we got today. We went with today. He tried a little bit. I think it got tweaked again. He tried."
Ochefu, a 6-foot-11 senior, is averaging 10.3 points and a team-leading 8.1 rebounds and 1.6 blocks. He is the only healthy player taller than 6-8 on Villanova's roster. With Ochefu sidelined for most of Thursday's game, Wright used junior forward Darryl Reynolds for 25 minutes, the most he has played since Ochefu missed three games with a concussion earlier this season.
"[Ochefu] gave us everything he's got," Wright said. "We have to try to rest him up and see if we can get him feeling better tomorrow."
Villanova will play the winner of Providence vs. Butler in one half of Friday's semifinals.
