The Jaguars signed quarterback Keith Null to the practice squad and waived defensive tackle Kommonyan Quaye.  This is Null's second stint on the club's practice squad.

Null, 6-4, 220, was signed to the Jaguars practice squad on Sept. 28 and was waived two days later.  He was a sixth-round draft pick of the St. Louis Rams in 2009 and played in five games for the Rams as a rookie including four starts.  He completed 61.3 percent of his passes (73 of 119) for 566 yards with three touchdowns and nine interceptions.  He spent the 2010 preseason with the Rams before he was waived during final cuts. 

A native of Lampasas, Texas, Null played collegiately at West Texas A & M where he threw for more than 9,000 yards in two seasons.
