LA VERNE -- The old windowless gym on the campus of Lutheran High makes for great echoes, and a thunderous dunk by Grant Jerrett easily reverberated across its walls Tuesday night.
Then, a loud thud. Deep gasps followed, and the building went hush.
Jerrett was flat on his back, clutching a left ankle that, recently, has been given him issues. He had tweaked the ankle yet again, rolling it on an opposing player's foot on his way down from an explosive and, what turned out to be, unlucky dunk.
"It's pretty bad," Jerrett said. "It's something I've been dealing with and I've been trying to strengthen the ankle. I don't know. I have to deal with it, I guess."
To make matters even gloomier it was senior night at Lutheran, and Jerrett spent it on the bench with a towel over his head and his elevated left ankle resting on a chair. The Trojans, ranked No. 9 by ESPN Los Angeles, faced little trouble without the top-rated senior in the Southland, routing Ribet Academy, 89-60. The ankle injury, though, is a major concern for the back-to-back state champions.
Jerrett estimates that he'll only be sidelined a day or two, but his status for Saturday's matchup at top-ranked Mater Dei is up in the air, according to Lutheran coach Eric Cooper.
"The playoffs are the most important thing," Cooper said. "There's no need for him to play Saturday. He'll want to play, but we'll see."
Fellow seniors Cameron Osorno and Brandon Shaw were recognized at halftime, with their parents joining them at half-court as Cooper spoke on a microphone. Jerrett, meanwhile, remained seated as his parents walked across the floor to embrace him on the bench.
"I'm disappointed, but we won," said Jerrett, who before the injury had three field goals in the game's first three minutes.
It was a bounce-back win for Lutheran (17-5), which was coming off an overtime loss to City Section power Westchester. Guard Eric Cooper Jr. had 20 points and Osorno added 17. Freshman point guard Tyler Dorsey had 28 for the Ribet Fighting Frogs (12-8).
The Trojans play Renaissance Academy at L.A. Valley College on Wednesday before Saturday's highly anticipated Nike Extravaganza battle in Santa Ana.
Jerrett is hopeful that he will play.
