The Chargers have signed kicker Roberto Aguayo to a reserve/future contract, the team announced Wednesday.Aguayo was a second-round pick in 2016 by the Bucs, who traded up to draft the Florida State product. But Aguayo missed nine of his 31 field goals as a rookie, and he was waived by Tampa Bay last August. Aguayo, 23, spent time with Chicago and Carolina this season but didn’t attempt a kick. The futures contract essentially gives him a chance to earn a roster spot during the Chargers’ offseason organized team activities and training camp.The Chargers finished last in the league in field goal percentage this season, making 20 of 30.RYAN RETURNS: Falcons quarterback Matt Ryan said he will be ready for Saturday’s NFC division game at Philadelphia after missing Tuesday’s practice for personal reasons. Ryan was back with the team for Wednesday’s practice. He didn’t disclose details of his absence but indicated he was attending to a family matter. "I just want to thank everybody for their support and outreach. It means a lot to me," he said. "I’ve always tried to keep my family life private, and I hope you can respect that and I’d like to continue to do that moving forward." Ryan and his wife, Sarah, announced in November they expect to become first-time parents in April with twins.JAGUARS: Backup linebacker Blair Brown sprained his left ankle during practice, a potentially big loss considering starters Telvin Smith and Paul Posluszny are dealing with injuries. Brown was wearing a walking boot and using crutches to get around, saying he "landed on it wrong" during a drill. Coach Doug Marrone praised Brown earlier in the day, saying he played well in an AFC wild-card victory against Buffalo last week. Brown filled in for Posluszny, who left the game with an abdomen injury.
