Mauga had surgery Friday to repair a torn pectoral muscle, suffered Monday night in the 23-17 loss to Houston.
Ryan said both had "successful" procedures, and the players are expected to be ready to participate in offseason workouts.
Allen was waived after the preseason on Sept. 1, but the Jets signed him to the practice squad the next day. In four seasons at South Carolina, Allen had 198 tackles, including 20 for a loss, four interceptions and six forced fumbles.
NOTES: G Matt Slauson had no comment on his planned appeal for his $10,000 fine by the league for his peel-back block on Houston's Brian Cushing, who suffered a season-ending knee injury on the play Monday night. Both he and Ryan have insisted that it was a legal hit. "I don't really want to get into it," Ryan said. "I've said from Day 1 and I'll stick with it: I know the intent of Matt Slauson was never, never to injure Brian Cushing. It's unfortunate that that happened. Cut blocks happen all the time in this league and we're a team that very rarely cuts people and things. It's an unfortunate part of the game and you don't wish that on any player. Matt obviously felt terrible when the young man was injured, as we all did." ... Colts backup QB Drew Stanton recently told The Indianapolis Star that the Jets told him he "was going to get a chance to play" if Mark Sanchez struggled after they signed him in the offseason. "I don't remember that," Ryan said. "I just know this: I read part of his comments, I felt that we had our quarterback, that we weren't going to draft a quarterback because we felt really good about our quarterback situation." Less than a week later, the Jets traded for Tim Tebow and fulfilled Stanton's request to be dealt. "With Drew, it wasn't like we said, 'OK, now we've got you under contract and you're going to be here regardless," Ryan said. "We never wanted to mess him over. That wasn't our intent when we signed him." ... Ryan, defensive coordinator Mike Pettine, linebacker Bart Scott and other Jets are wearing blue "CHUCKSTRONG" shirts, and will take a photo and send it to Indianapolis coach Chuck Pagano, who is hospitalized while being treated for leukemia. Ryan, Pettine and Scott spent time in Baltimore with the Ravens together.
