ASHBURN, Va. -- A little this and that as the Washington Redskins returned to work Monday:

• Tracy Porter re-injured his hamstring in practice Saturday and did not practice Monday. The big knock on Porter throughout his career has been durability. Last season was the first time Porter played 16 games -- and only the second time he's played more than 12 -- in six seasons. The Redskins want Porter to play in the slot. Rookie corner Bashaud Breeland has worked there this summer, but is still learning the position.

• The Redskins finalized their 10-member practice squad, signing safety Akeem Davis, as expected, and linebacker Chaz Sutton. Davis was cut by Washington Sunday after it claimed Duke Ihenacho off waivers. Tampa Bay cut Sutton on Aug. 25 after signing him as an undrafted free agent from South Carolina in May. The 6-foot-5, 263-pound Sutton played defensive end in college.

• The Redskins placed safety Phillip Thomas on the practice squad for the same reason they did it with Chris Thompson. They have questions about his ability to stay healthy and want to see him work for an extended time without getting hurt. Thomas visited his foot specialist in North Carolina over the weekend to determine the cause of soreness in his foot. It's the same foot that suffered a Lisfranc injury last summer. Thomas did not practice Monday and might not be ready for another week or so. The Redskins do like him, but being available is a must.

• The Redskins did not want to put linebacker Darryl Sharpton on injured reserve, but coach Jay Gruden said his sprained ankle was "worse than we anticipated." Sharpton suffered a high ankle sprain in the first preseason game against New England and did not think he'd miss that much time, though this type of injury can linger. "We had high hopes for Darryl," Gruden said. "It just didn't get any better for him. We want to make sure we take care of it the right way."
