They're two dynamic players in Buffalo's offense, but heading into Sunday there is a real possibility that the Bills could be without both Fred Jackson and Sammy Watkins in their game against Kansas City.

Jackson and Watkins were both listed as questionable on the team’s injury report following practice Friday. Watkins was unable to practice for most of the week after aggravating a groin injury in Wednesday's practice.

"I've just been dealing with it and I've just got to get better," said Watkins. "Hopefully the coaches and the staff get me better."

Watkins did not practice on Thursday or Friday, which makes head coach Doug Marrone a bit uneasy about playing Watkins should he be healthy enough to play come Sunday.

"I think it's something to be concerned about obviously," said Marrone. "It's the same as it is with all the players. They all have to be ready to go in understanding what we do. We're just going to have to take some time and see where we're at before we make any decisions."

Watkins confirmed that he had an MRI on his groin earlier in the week, but did not reveal the results of the imaging. He's never had a serious injury in his entire playing career, so it's hard for him to assess the severity of his current ailment.

"It's a groin. With those you've got to be careful. You've got to be smart," he said. "You really don't know whether you're right or not. For me it's just listen to the trainers and listen to the coaches."

Marrone did point out that there's still time before Sunday's game, but also indicated there is no plan to have Watkins test his ailing groin at Saturday's practice.

"No, I don't think it is (the plan) until the trainers tell me he can go," said Marrone. "The guy can't practice."

Jackson practices, but questionable

The situation would appear on the surface to be better for Fred Jackson, who was able to practice for three straight days albeit on a limited basis. Marrone however, wasn't very optimistic about Jackson's availability.

"We're still not where we need to be for him to go out there. We're still progressing with that," said Marrone.

Jackson believes he's shown the athletic trainers, medical staff and the coaches everything he needed to in order for him to be cleared to play.

"I think so. I was able to show that I can get out there and move around well. The thing we have right now in our favor is we have two guys that are capable of shouldering that workload," said Jackson of fellow running backs Boobie Dixon and Bryce Brown. "So it'd be one of those things where they'll have a conversation and go through that process and see if they feel it's something where they need to keep me out for another week or have me come up."

Naturally it would be Jackson's preference to play Sunday, but he knows the final call is not his to make.

"It would be good to get back out there, but like I said we'll see what the process holds," he said. "We've got a couple of days, see how it reacts and see what they decide."

Goodwin probable

Meanwhile the news is promising for WR Marquise Goodwin, who was able to practice all week, though limited, as he tries to return from a hamstring injury. Goodwin has missed each of the last two games after suffering the hamstring injury in practice back in Week 7.
