Report: Fred Jackson (groin) likely out for Bills vs. Dolphins

Buffalo Bills running back Fred Jackson (groin) is "likely out" for Thursday's game vs. the Miami Dolphins.

Buffalo Bills running back Fred Jackson (groin) is "likely out" for the Thursday Night Football game vs. the Miami Dolphins, according to Tim Graham of the Buffalo News. Though Jackson is listed as "questionable," NFL.com reports his groin injury has worsened.

Jackson injured his groin during Buffalo's Week 7 victory over the Minnesota Vikings and missed the following week's game against the New York Jets. The injury was initially expected to keep him out for as many as four weeks, but after the Bills' Week 9 bye, Jackson was active against the Kansas City Chiefs, rushing three times for 10 yards.

On the season, Jackson is Buffalo's second-leading rusher behind C.J. Spiller with 58 carries for 249 yards and one touchdown.

Jackson, 33, signed a one-year extension with the Bills in August. He would've otherwise hit the free-agent market in March, not long after he turned 34.

Jackson is coming off a season in which he played in a full 16 games for the first time since 2010. He's spent the entirety of his eight-year career with the Bills after going undrafted in 2003.
