The Texans have signed fullback Cecil Sapp as the Broncos’ pipeline continues to flow to Houston.  The 29-year old Sapp played in 16 games (8 starts) with the Broncos last season and he carried the ball 18 times for 59 yards (3.3 ypc) with 2 TD runs.  He also caught 14 passes for 51 yards (3.6 avg) with a TD grab last season.  Sapp has played in 49 games (9 starts) in his NFL career and he has carried the ball 49 times for 223 yards (4.6 ypc) with 2 TD runs.  He has also caught 24 passes for 102 yards (4.2 ypc) with a TD grab.  Look for Sapp to back up Vonta Leach at fullback and he could get some carries at halfback if the Texans’ suffer some injuries there.
