The Packers formally placed rookie number one pick Derrek Sherrod on injured reserve Tuesday after he shattered his lower right leg against the Kansas City Chiefs.  The Mississippi State tackle underwent emergency surgery in a Kansas City hospital last Sunday night after the 19-14 loss to the Chiefs.  He's expected to return to Green Bay by the end of the week.  With starting right tackle Bryan Bulaga working through a knee-cap strain, the Packers were dangerously thin on the offensive line.  To take Sherrod's roster spot, the Packers signed former Chiefs tackle Herb Taylor out of TCU. Taylor (6-4, 305) was a 6th round pick of Kansas City in 2007.  He played in 18 games as a backup, staring once before getting released.  He was signed by Denver but was cut in 2009 and Taylor failed to make rosters in each of the last two training camps of the New York Giants and again, the Broncos.  Depending how long Bulaga sits and with Chad Clifton possibly just returning to the practice field on a limited basis this week,  Taylor will almost certainly suit up Christmas night against the Chicao Bears.
