DJ Chark isn't sure exactly what's going on with his sore left ankle, but the Detroit Lions receiver knows enough to believe he will play again this season.
Chark missed his second straight practice with an ankle injury Thursday and likely will miss the game Sunday against the Dallas Cowboys, his third straight. He declined to set a timetable for his return Thursday, when he called his injury "frustrating" and wore a walking boot on his foot as he talked with reporters in the locker room.
"The boot makes it look way worse," Chark said.
