Crockom, who was expected to be one of the Griffons' leading pass catchers this year, left the field on a cart Saturday before being taken to a local hospital.
Head coach Jerry Partridge wasn't sure on the wideout's timetable, but isn't completely ruling out a possible return late in the season.
"I don't know if it's six to eight (weeks), because he broke two bones in his arm. It was pretty graphic, and they put a bunch of screws in him," he said. "He is a senior, so things are different. It's kind of up to a senior and what they want to do sometimes."
"Obviously, he's a month and a half, maybe two months away... maybe more. Right now, it looks like his career and season are over, but I don't know."
Crockom has hauled in seven passes for 79 yards through three games, but hadn't found the end zone yet. His absence will mean a boost in playing time for redshirt senior Andrew Molloy, redshirt sophomore Dee Tolliver, and others.
"You'll see guys step up. They have been. Tolliver's been making plays, Derek Libby's a great player, Josh Walker is a kid who'll get more time. Offensively, we've got 13 or 14 guys we've been messing with."
Crockom is also listed on the depth chart as Travis Partridge's backup at quarterback. Coach Partridge says the decision on the new backup is still up in the air.
"We're going to have to make a decision probably on who legitimately is that guy."
