Hall injured his groin during training camp practice on Thursday.
The 31-year-old, who is second among active NFL players with 43 interceptions, left Washington's joint practice session with the Texans on Thursday and did not return. Following the injury, he watched the rest of the three-hour practice from the sideline.
“I'm going to get checked out, figure out what's the issue,” Hall, who was sidelined for offseason workouts following two Achilles surgeries last year, told reporters. “I didn't hurt my Achilles. But definitely my groin is hurting a little bit right now.”
Hall said his groin felt tight before practice, but decided to participate because the Redskins were already without fellow cornerbacks Bashaud Breeland (knee), David Amerson (shoulder) and Tevin Mitchel (shoulder).
Hall first experienced his groin injury Thursday while backpedaling and cutting to cover a receiver.
“I don't feel it's anything too major, but it definitely hurt enough for me to have to limp off,” Hall said.
Hall injured his Achilles during Week 3 of the 2014 season, and then re-injured it in October on a scooter, requiring a second surgery.
He is signed with Washington through 2017 and is set to make $4.8 million in 2015.
