Mark Sanchez has his sights set on returning to the field this season — as the Jets’ starting quarterback. Sanchez was placed on short-term injured reserve Saturday, meaning he will not be able to play for the next eight weeks while he recovers from an injured right shoulder. ‘‘As far as making a decision that’s best for the team and best for my medical health, we’re all on the same page,’’ Sanchez said during a conference call. Sanchez injured his right shoulder after replacing rookie Geno Smith in the fourth quarter of the team’s third exhibition game against the Giants. He has opted to try to rehabilitate the injury rather than have season-ending surgery. The exact nature of the injury has not been revealed, but some published reports say it is a partially torn labrum. Sanchez was examined by team doctors, Dr. James Andrews, and consulted with several others last week . . . The Jaguars signed receiver Jeremy Ebert, a 2012 Patriots’ seventh-round draft pick, and cornerback Marcus Burley off their practice squad, and waived guard Jacques McClendon and defensive end Chris McCoy . . . The Redskins signed kicker John Potter in case Kai Forbath (groin) is unable to kick in Sunday’s game against the Packers. To make room for Potter, the Redskins released fourth-string quarterback Pat White.
