Stabler told BamaMag.com on Tuesday that he had been getting fluid drained from his knee but that he was trying to work through it.
He had arthroscopic surgery on the same knee before Alabama's spring football practice in February, causing him to miss most of spring drills.
"It was hurting him," Alabama Head Coach Mike Shula said. "They drained his knee and it felt better. (Then) he scrimmaged and did a decent job but he felt sore the next day. So we took another MRI and that's when they found the slight tear in the cartilage."
Shula said Stabler's surgery this morning was successful.
Shula also updated the status of Antoine Caldwell, who suffered a sprained ankle in Monday's scrimmage.
"He'll miss the rest of this week. Hopefully get him back at some point next week," Shula said.
With right guard Stabler and left guard Caldwell out, Mark Sanders and Taylor Britt have assumed repetitions with the first-team unit at those respective positions. Britt is also considered the second-team center.
"Taylor Britt would also move in as the second team center, but if something happened there Evan Cardwell would be our second team center."
Shula said Britt is valuable because he can play both guard spots as well as the center position.
"There's other guys still in the mix, Justin Moon, and hopefully we can get those (injured) guys back," Shula said. "B.J.'s disappointed but it was the best thing instead of having him try to go through the whole year. If it was the last two weeks of the season it might be a different story. Hopefully we'll get him back as quick as we can and he'll have a lot of football this year."
