JACKSONVILLE – The injury list grew a bit shorter Wednesday.

That was good news considering the Jaguars' injury situation through six regular-season games, with the most significant news Wednesday involving the team's top wide receiver.

That's Allen Robinson, who left Sunday's loss to Houston with a lower leg contusion.

Robinson, who leads the Jaguars with 488 receiving yards and five touchdowns, practiced on a limited basis Wednesday afternoon – a day when only six players were held out of a non-padded practice at the Florida Blue Health and Wellness Practice Fields.

The team will practice again Thursday in Jacksonville before traveling that evening to London for a home game Sunday against the Buffalo Bills.

"We got a lot accomplished," Bradley said as the Jaguars (1-5) prepared to play the Bills (3-3) at Wembley Stadium in London Sunday at 9:30 a.m.

Running back T.J. Yeldon, who missed the Houston game, missed practice Wednesday with a groin injury. Others not practicing were wide receiver Allen Hurns (thigh/ankle), wide receiver Marqise Lee (hamstring), safety James Sample (shoulder), safety Johnathan Cyprien (calf) and defensive end Chris Clemons (veteran day off).

Hurns, Cyprien and Clemons all played against Houston, while Lee has missed the last three games and Sample has been out the last two. Bradley said he doesn't expect Lee to practice this week, and that the second-year veteran may not make the trip to London.

Running back Bernard Pierce, who missed Sunday with a concussion sustained the previous week at Tampa Bay, has been cleared from the concussion protocol program and worked full on Wednesday.

Tight end Julius Thomas (chest/hand) worked full in a red, non-contact jersey.

Yeldon, the Jaguars' leading rusher, worked out before the loss Sunday before being deactivated, and ran on the side during practice Wednesday.

"I think they (trainers) were going to see how he ran on the cuts today," Bradley said.

Bradley said Wednesday's non-padded practice featured a tempo similar to a normal regular-season Thursday session. He said the team also added an extra six-play period to practice with an emphasis on "things we need to work on."

Bradley said Wednesday's non-padded work also allowed four or five players who ordinarily wouldn't have been able to practice.

"It was nice to get guys out there and able to practice," he said. "Sometimes, at this time of year, it's good to change it up and give them a no-padded day."

The Jaguars have left for London early in the week the past two seasons, leaving on Monday before a loss to the San Francisco 49ers in 2013 and leaving from Cincinnati on Sunday night before a loss to the Dallas Cowboys last season.

Bradley said the later departure before this season's London game is about trying to find the optimum schedule.

"We're still trying to get an idea, to get a feel for how fast our guys acclimate to it," Bradley said, adding that the later departure time is good for coaches as they game plan and prepare: "We're in our offices, we can watch tape: everything's here. It's still a lot of work for our trainers, but there are fewer things that need to go over because of the lateness we're leaving in the week.

"We have (research on) all the teams and how successful they've been. There have been teams that have gone over there early and beat the team that has gone over there late. I think it still comes down to how you prepare and how you play. But you look at everything."
