New York Jets linebacker Vernon Gholston was listed as doubtful for Sunday's game against the Jacksonville Jaguars because of a strained hamstring. Gholston, the Jets' first-round draft pick last year, didn't practice all week after tweaking his hamstring Monday in the team's first workouts following the bye-week break. "He did not participate, so that's going to be very doubtful that he plays," Jets coach Rex Ryan said Friday. Despite showing some improvement since his disappointing rookie season, Gholston is still looking for his first NFL sack. Source: Associated Press
