Updated at 1:15 p.m. with surgery ending

The back injury that bothered New York Giants defensive end Jason Pierre-Paul last season required surgery after all.

Pierre-Paul had the operation today in Los Angeles and is expected to be ready to play when the season opens, ESPN reports. The injury, Ralph Vacchiano of the New York Daily News reports, is a herniated disk that will require three months of recovery and rehab.

He managed to get through the 2012 season by getting injections, but his productivity dropped off. Pierre-Paul, the 15th overall pick in the 2010 NFL draft, had only 6.5 sacks, after his career-high 16.5 in 2011.

The Giants need Pierre-Paul to recover swiftly, with Osi Umenyiora now playing for the Atlanta Falcons. That leaves Justin Tuck and Mathias Kiwanuka as the starters with Adrian Tracy and Damontre Moore the backups.
