Saban emphasized that he did not want to delve too deeply into the medical area, which is not his field of expertise.
The coach said, "They will cotinue to evaluate Zeke Knight, but he was cleared Friday that he is able to go. They had finished their testing from however long it has been since he had his surgery and the doctor cleared him to go."
No surgery for Knight had ever been revealed prior to Saturday.
Saban said that Knight did not go through the off-season program.
"We're pleased that he is out there and able to get repetitions," Saban said. "He's a well-conditioned enough athlete that it doesn't seem to affect him–his ability to sustain is not affected by not going through the off-season program."
Knight, 6-4, 230, is an upcoming senior defensive end from Wedowee. Knight was a member of Alabama special teams and back-up wide receiver as a freshman in 2004 and sophomore in 2005. He had 21 receptions for 224 yards and one touchdown.
Last season he moved to defense, where he was expected to be a passing down rush specialist. He had four tackles, including one for lost yardage, and caused a fumble in the first four games, then missed the rest of the year with his ailment.
