(WHBL-Learfield) - Green Bay Packers’ defensive coordinator Dom Capers says he’ll have to get creative to make up for a shortage of safeties. Rookie Morgan Burnett is out for the season after tearing the A-C-L ligament in his left knee in last Sunday’s win over Detroit. And Capers says he’s working on new player combinations to create more flexibility in the secondary. Backup safety Charlie Peprah is still getting over a thigh injury. And the man Burnett replaced, Atari Bigby, is out for at least two more games and maybe longer as he comes off ankle surgery. Capers created the “Psycho” package – which includes only one down lineman – to make up for an injury shortage. The same was true for the “Big Okie” package, in which linebacker Brandon Chillar plays the second safety spot with more flexibility. But Chillar is still coming off a shoulder injury – and he might not be available on Sunday when the Packers play at Washington. Jarrett Bush has also played at that spot. And Clay Matthews or Charles Woodson could move into that slot as well. Capers and safeties’ coach Darren Perry both say it would be hard to bring in an outsider as a replacement who has not played in the Packers’ system. Derrick Martin replaced Burnett last Sunday. And the Packers could bring up safety Anthony Levine from their practice squad.
