The Jets could be without starting strong safety Jim Leonhard for a while due to surgery he has had to repair a thumb that he fractured against the Jags last Sunday.  Leonhard has played in 9 games this season for the Jets and he has 43 tackles, 4 tackles for a loss, 1.5 sacks, 4 passes defensed and he has 1 interception.  The Jets will also miss Leonhard on special teams as he has been the punt returner.  Leonhard has returned 21 punts for 173 yards (8.2 avg) this year for the Jets.  Eric Smith will replace Leonhard on defense.  He has played in 9 games for the Jets this season and he has 27 tackles, 1 tackle for a loss, 4 passes defensed and 1 interception.  Smith should be able to do a decent job at safety while Leonhard is healing.
