Charter Oak’s Travis Santiago sprains ankle at practice, may miss Thursday’s championship showdown at Chino Hills …

Charter Oak standout quarterback Travis Santiago may miss Thursday’s Sierra League championship game at Chino Hills after spraining his ankle in a freak accident before the Chargers’ practice on Wednesday afternoon.

Santiago removed his helmet and placed it next to him while he made warm-up throws prior to Wednesday’s walk-through. After getting a drink of water, he went to find his helmet and accidentally stepped on it, spraining his ankle in the process.

“It was a freaky thing,” Charter Oak coach Lou Farrar said. “You can’t plan that.”

At Farrar’s urging, Santiago left to have x-rays performed. Results will not be known until Thursday morning, but the doctor called it a bad sprain and Santiago was placed in a walking boot and given crutches.

Farrar said that at this time he is not expecting Santiago to play on Thursday. Sophomore Kory Brown will likely get the start.

“I’m really not expecting him to play, but Travis is a tough kid,” Farrar said. “If his doctor says he’s OK, his family says he’s OK and Travis says he’s OK, then we’ll go with him.

“It’s a doctor and family decision, not a coaches decision. We’ll be OK. We have 45 other football players on this team.”

Charter Oak did get some good news, though, on Thursday. Sophomore running back Kurt Scoby is expected to play, but will not be at 100 percent. Scoby suffered a sprained ankle in last week’s loss to Damien and has not practiced this week.
