Sammy Watkins, Fred Jackson active

— -- ORCHARD PARK, N.Y. -- Buffalo Bills wide receiver Sammy Watkins and running back Fred Jackson are both active for Sunday's game against the Kansas City Chiefs.

Both players were listed as questionable with groin injuries.

Watkins left last Wednesday's practice with the injury and did not participate in practice Thursday or Friday. The rookie leads the Bills with 38 catches for 590 yards and five touchdowns.

Jackson was carted off during an Oct. 19 win over the Minnesota Vikings and did not play in the Bills' win over the New York Jets the next week. He returned to practice last Wednesday.

He tweeted that he would play shortly before the Bills released their inactive list for Sunday's game.
