Cleveland Browns quarterback Jake Delhomme didn't practice again Thursday because of an injured right ankle.
Browns coach Eric Mangini said Delhomme has made progress with his ankle, which he hurt while throwing an interception in the closing minutes of the first half in Sunday's season-opening loss at Tampa Bay. Delhomme has been wearing a walking boot to stabilize his ankle.
If Delhomme is sidelined, backup Seneca Wallace will make his 15th career start. Wallace took all the snaps with Cleveland's first-team offense Wednesday and was expected to do so again Thursday.
"I couldn't tell you now where it's going to be at the end of the week," Mangini said.
"It depends on how much he's able to do in terms of getting some reps," Mangini said. "He's not going to miss a beat in terms of preparing for what (the other team is) doing."
