Arizona Wildcats safety Adam Hall tore his ACL in Saturday's spring game, continuing a disturbing trend of offseason injuries for the UA football program. Hall tweeted the news around 7:30 p.m. tonight, four hours after the 98-play scrimmage ended. The injury puts Hall's football future in doubt:    Players with torn ACLs typically need between six and nine months to heal fully. 

"If you didn't hear, now you know," Hall tweeted. "Thank you for all the prayers." 

Hall appeared to injure his  knee when he de-cleated wide receiver Sean Willett on a passing play midway through Saturday's scrimmage. Following the spring game, first-year coach Rich Rodriguez reported that Hall "tweaked his knee a little bit," and that the Wildcats' training staff would re-evaluate before Monday's final practice of spring. 

Saturday's injury is the second in as many years for Hall, who tore his ACL last March and missed all of spring and fall camps. He played in the Wildcats' Oct. 8 loss at Oregon State, but was shut down for the season after experiencing soreness and ill effects from the injury.
